“Do it. The Marines are wrapping things up at Verdun. And Charlie out there has just become our number-one priority.”
But one squadron against a frigate-sized ship of unknown capabilities and escorting fighters—those were not good odds. He flashed an order to the two capital ships now maneuvering down to low Earth orbit, ordering them to join the chase as well, but they almost certainly wouldn’t be able to catch up with Charlie One.
Quickly, Gray searched the fleet network, looking for a warship positioned in such a way that it could intercept the fleeing alien. Let’s see … Mars and Jupiter were both at completely wrong angles, with Earth between them and the alien ship just now. There was a small USNA flotilla still out in Saturn space, watching over the newly recaptured stations at Enceladus, Titan, and the Huygens Ring Facility Observatory. However, at the moment, Saturn was a good 9 AUs out from Earth, which meant a time delay of seventy-two minutes for any message from America’s communications department to reach them.
There was a High Guard watchship, the Concord, in a good position within the asteroid belt—at Vesta, just to one side of the Sun and 3 AUs from Earth at this angle, with a time delay of twenty-four minutes. Better. Much better. High Guarders weren’t in the same league as line naval capital ships, but were designed to keep an eye on asteroids that might pose a threat to Earth—either by chance or through enemy action. Yet they were in the best position to handle Charlie One.
Gray called up the ship and its skipper’s personnel records. Technically, the High Guard was a Confederation organization, jointly run by Geneva and by the USNA military through Mars HQ, but that had been the situation before the civil war. For the past year, the High Guard had been primarily a USNA operation pretty much by default, since most of the personnel and ships had come from the United States.
Concord’s skipper was Commander Terrance Dahlquist … and he was a former USNA naval officer. Excellent.
“Comm,” he said. “This is Admiral Gray. Make to the Concord …”
And he began detailing what he had in mind.

“America is in pursuit, sir. They’ve cast off from the dock and are accelerating.”
“Do they have a chance in hell of running that ship down?”
Whitney looked uncomfortable. “Unknown, sir. That alien has legs.”
“What I would like to know,” Koenig said, leaning back in his chair and steepling his fingers, “is how an alien starship of approximately four thousand tons managed to get to Earth, to land on Earth, without being detected.”
“We’re … working on that, sir. It’s possible it was brought down as cargo. On a skycrane.”
Skycranes were space-to-ground transports used to get large quantities of both raw material and manufactured items from the manufactories in orbit down to Earth’s cities. Smaller goods went down the space elevators, of course, but large items, as well as multi-thousand-ton asteroidal material for those manufactories still on Earth, could more efficiently be lowered straight to the destination city.
Koenig shook his head. It had still been a gutsy move, since skycranes were legitimate military targets. If it were true, it meant someone on the other side had been gambling that the USNA was too thinly stretched to bother with what was obviously a civilian target.
And yet maybe it hadn’t been such a gamble after all. The USNA propaganda machine—and the Starlighters—had been pointing out endlessly to all who would listen that the USNA was not going after civilian targets (unlike the Confederation faction that had nanoed Columbus). Perhaps the aliens, whoever—whatever—they were, and their Confederation hosts, had been counting on that.
The whole question of the Confederation’s relationship with off-worlders, the Sh’daar in particular, was a nagging and unrelenting source of concern for Koenig and his military staff. That the Confederation had long wanted to agree to the Sh’daar demands—their ultimatum requiring Humankind to give up certain technologies—was well known. Hell, that, more than anything else, had been responsible for the political rift that had led to the civil war.
Koenig was not going to permit a nonhuman civilization to dictate either the direction or the limits of Earth’s technological development, and he was pretty sure that most people all over the planet agreed. What had the aliens offered Geneva, he wondered, that had led the Confederation government to agree to such a thing?
And had that mystery ship grounded in North India had anything to do with the offer?
If they could stop the aliens and open some kind of dialog with them, they might be able to find out. For a long time, the USNA had been fighting in the dark, not certain of just who the enemy was, or what their relationship might be with Geneva.
But right now the alien ship was leaving Earth like the proverbial bat out of hell, boosting at 50,000 Gs, and there was no guarantee whatsoever that USNA forces would be able to stop it.
He considered relaying a message to Admiral Gray urging him to do so, and decided against it. No amount of urging would improve the odds.
And Koenig knew that Gray would be giving his best effort no matter what it was that he set out to do.
All Koenig could do was wait and watch …

The four Starblade fighters by now were well past India, and were passing just to the south of the Singapore space elevator. Connor could see the tower in the distance with her naked eye —a bright white line scratched from Earth up into heaven, laser-beam straight, emerging from the heart of a vast and sprawling metropolis that stretched from the tiny equatorial island of Pulau Lingga, 150 kilometers northwest to Singapore, south to Sumatra, and covered the surface of the sea in between.
The Americans were on a highly inclined orbit, one that had swung southeast from above France to just brush the southern tip of the Indian subcontinent, and then bypass the Singapore space elevator a couple of thousand miles south of the equator. Even from a distance of 2,000 kilometers, though, the elevator was a spectacular sight, gleaming in the midday sun overhead.
“Confirm we have clearance to accelerate,” Mackey said over the tactical channel, “Boosting in five … and four … three … two … one … punch it!”
And the Singapore elevator and the city at its foot vanished, wiped away as the four fighters switched on their forward gravitic projectors and accelerated outbound at seventy thousand gravities. After one second, the Starblades were moving at 700 kilometers per second, and had already traveled 350 kilometers out from Earth. After one minute of steady acceleration, their speed had increased to 42,000 kilometers per second, and they’d covered 1.26 million kilometers—well over three times the distance of the moon from the Earth. Aft, Connor could see the Earth and moon together, a pair of full-lit disks already rendered small by distance, and swiftly growing smaller with each passing second.
Ahead, and just to starboard, the sun grew visibly larger moment by moment.
“Hey, Skipper?” Connor called. “I don’t think we’re going to catch them.”
“We follow orders, Lieutenant.”
“Yeah … but they’re going to be pushing c in one more minute. And we won’t be there for another six.”
“Just follow your orders, Lieutenant. There’s nothing else we can do.”
Charlie One was boosting at fifty thousand gravities, about the same as a Krait ship-to-ship missile. Quite possibly, it was limiting its boost to accommodate its Todtadler escorts, which had an upper limit of fifty thousand Gs.
Regardless, the problem was one of straightforward TDA mathematics—time, distance, and acceleration. When Charlie One and its Confederation escorts reached about 99.7 percent of the speed of light in another sixty seconds, they would be 63.9 million kilometers from Earth. When the Black Demons reached that same speed in another six minutes, they would be 89.4 million kilometers from Earth—six-tenths the distance between the Earth and the Sun.
But by that point, Charlie One would have been traveling at near-c for five full minutes, covering an additional 90 million kilometers, for a total of nearly 154 million kilometers.
In other words, both hunter and prey would be traveling at the same speed, but the hunters would still be almost 65 million kilometers behind Charlie One.
An ancient sailing aphorism held that a stern chase was a long chase, but it was worse than that—a lot worse. There simply was no way to close that gap. No matter how high the acceleration, the dead hand of Einstein had long ago decreed that there was no way for material objects to pass—or even reach—the speed of light. According to the math governing relativistic calculations, the faster a ship went, the more massive it became, the shorter it became along its line of travel, and the more energy was required to accelerate it, a kind of feedback effect that led to the ship acquiring infinite mass and zero length at the speed of light, thus requiring infinite energy to move it faster.
The way the universe had been put together, it simply couldn’t be done. Even with all the energy available from the vacuum, the fighters might shave a few more decimals from that 99.7 percent of c, but they could never reachc, never mind surpass it.
But there was a loophole. Interstellar travel in anything less than decades would not have been possible without it. The Alcubierre Drive had been developed 284 years earlier, a realization of principles first described by physicist Miguel Alcubierre in 1994. Using the same projected singularity technology, an Alcubierre Drive ship pulled itself into an enclosed bubble of spacetime. There was nothing in physics that said that such a bubble couldn’t travel faster than light; indeed, in the earliest instants after the big bang, during the inflationary epoch, space itself had increased in volume by an estimated 10
times in 10
seconds—which meant that points within that expanding volume would be moving away from one another at many, many times the speed of light. A starship imbedded inside that spacetime bubble would be motionless relative to the space immediately around it, and therefore would not violate the ultimate-speed law of the cosmos.
Alcubierre Drive had several key limitations, though. For one, a ship was effectively “alongside space,” and therefore unable to communicate or interact with anyone in “real space” until it emerged. Another—and the one Connor was focusing on at the moment—was that a ship needed a fairly flat gravitational metric when the drive was engaged. Shipbuilders had been working on that problem for centuries, with no discernable results. So a ship still couldn’t go into faster-than-light drive until it was eight to ten AUs out from a star of Sol’s mass—the distance, roughly, of Saturn at its farthest from Earth.
No, the real problem was that none of this necessarily applied to Charlie One. It was an alien ship, of unknown potential and technologies. For all any human knew, it might pop into Alcubierre Drive in the next few seconds, or within a couple of million kilometers of the sun. Connor decided, however, that that was extremely unlikely. If they could have done it inside of one astronomical unit, they would have done it by now. The fact that they hadn’t led Connor to speculate that they were aiming for a particular patch of sky, that they would continue accelerating past Sol and out into the outer system before engaging their FTL drive.
So the million-dollar question is, just what part of the sky might that be?
It was simple enough to superimpose a star chart over her fighter’s navigational data.
And the answer to her question was … surprising.

“The fighters are in pursuit, sir,” Admiral Armitage told Koenig. “They won’t catch the damned thing, though. Not unless either Charlie starts decelerating or they can shave another tenth of a percent off their velocity.”
“How good are the new designs at that sort of thing?”
“Mostly depends on the pilot,” Armitage said. “Things are happening awfully fast at those velocities, remember.”
Koenig nodded. He’d been a fighter pilot once, a very long time ago. “I do.”
As a fighter moved faster and faster, relativistic phenomena not only increased the vehicle’s mass, pushing it toward an impossible-to-reach infinity, but it also shortened the rate at which time—as measured by an outside observer—passed for the pilot, an effect called time dilation. The pilot experienced everything—the increase in mass, the compression of time—as perfectly normal; it was outside observers that saw basic constants of the universe shift and flow like water.
For fighters traveling at 99.7 percent of the speed of light, one minute objective—a minute as perceived by slowpoke left-behinds—was only 4.64 seconds. To observers back on board the carrier, the pilot would seem to be moving and speaking and living with extreme slowness.
The difference could be significant—and a real problem, especially in combat. Where a relatively stationary target had a minute to react to oncoming fighters, those fighters had only a few seconds. The best cybernetically augmented reaction times in the world couldn’t handle differences at such scales.
In fact, getting anything done when you were up against an unaccelerated opponent was dangerous when a decision or an action taking a handful of seconds was in fact a whole minute long outside of the pilot’s frame of reference. At least, Koenig thought, in this case both the fighters and their quarry were pushing c, and the time difference between their relative frames of reference was trivial.
That was one reason that fighters sent at relativistic speeds toward an enemy target generally decelerated before reaching their objective. Speed was life, as the old fighter-pilot aphorism had it. But in modern space-fighter combat, too much speed could put you at a serious disadvantage.
With all that in his mind, Koenig pulled down an in-head schematic from the America showing the relative positions and speeds of the alien vessel and the pursuing fighters. He began pumping through some simulations. If the fighters could increase their velocity by an additional tenth of a percent of c, their speed, relative to their quarry, would be 30,000 kilometers per second and closing.
At this point, the fighters would be trailing the enemy by …
He let the calculations run themselves through: 65 million kilometers. With a closing velocity of 30,000 kps, that meant an intercept in another thirty-six minutes.
Like a dog chasing a hovercraft, though, what they would be able to do with the alien once they actually caught it was still unknown.
And it was still all based on the “if” of moving closer to the speed of light.

Commander Terrance Dahlquist read the message as it came through, direct from Admiral Gray and the star carrier America. He wasn’t quite sure how he should feel about this … or what he was going to do about it.
Originally a branch of the North American military, the High Guard had been established in the wake of the Wormwood Incident in 2132, when a rogue Chinese squadron had dropped a small asteroid into the Atlantic Ocean. Later, official control had been handed over to the Earth Confederation, since it was operating in the defense of the entire planet. Concord’s mission was to monitor operations near asteroids, and to stop unauthorized attempts to manipulate their trajectories. In those cases where either asteroids or ore samples were legally being injected into Earth-approach orbits, the Guard tracked them, double-checked the calculations, and tried to make certain that Earth or other population centers across the solar system weren’t endangered.
Further, the High Guard made sure Vesta was always closely watched. The site of a large, mostly automated mining facility, the asteroid possessed a set of ten-kilometer-long magnetic launch rails designed to fire canisters of nano-extracted and -processed ore from the jumbled, frozen crust into low-energy transit loops that would bring them within capture range of Earth-based capture vessels within three to five years, depending on the constantly changing angles and distances between worlds. Fearing that terrorists or other rogue forces might easily change the launch parameters and turn the launch rails into titanic long-range weapons ideal for planetary bombardment, the High Guard was stationed there as protection against that scenario. In truth, it was not very likely to happen. For one thing, it would be a high-risk, low-reward endeavor, since incoming canisters were closely followed by radar and lidar, and intercept missions could easily nudge them into harmless orbits. But Earth’s governments remained nervous about falling rocks, especially deliberately chucked falling rocks, almost three centuries after Wormwood Fall, and High Guard frigates like the Concord were there to provide some measure of reassurance.
They were not designed to engage alien starships of unknown potential.
Dahlquist wanted to shoot a message back to Gray. The problem was that the High Guard, though technically a part of the USNA Navy during the current hostilities with the Confederation, was not under Navy jurisdiction, and a line officer like Gray did not have the authority to order High Guard assets off station.
Of course, the real reason he was hesitating had more to do with Gray’s background.
Like most USNA Guard and Naval officers, Dahlquist was a Ristie. The United States of North America was supposed to be a classless society, but that was fiction and always had been. Always there were “haves” as distinguished from “have-nots.” Money was not as big a factor in modern society as it once had been; the nanotech revolution had long ago made wealth-based distinctions largely irrelevant. But power, especially the power available to those with better technology and better access to information, was another matter altogether. Nowadays, those who had more advanced electronic implant technology, those who had life extension and better nanomed support, those who had connections in the larger “have” networks of government and the military—those were the new social elite. Risties was the slang term for the cultural aristocrats who called the shots in modern civilization.
Of course, they would never use the term themselves.
They did, however, use the term Prim, and the fact was that Gray was a well-known Primitive. Sure, Gray had acquired that technology when he left the Manhat Ruins decades ago, but Dahlquist couldn’t shake the subtle prejudice against him and people like him. They hadn’t grown up with the tech, had never been completely comfortable with it … and that, in the minds of most Risties, was telling.
Dahlquist would never have admitted to technocybernetic prejudice, of course, but he couldn’t shake the nagging feeling that “Sandy” Gray didn’t really know what he was doing, that he tended to overlook some of the information available to him over the various data networks because he hadn’t grown up with the technology.
That in certain subtle ways, he wasn’t fully human.
And that, when all was said and done, was what it was all about. Humans were defined by their technology. That was one reason the USNA had been fighting the Sh’daar and, more recently, the Confederation: humans were what they were because of their tools, from fire to starships to neurocybernetic implants.
And yet, what it all came down to was that what Gray was ordering Dahlquist to do was technologically challenging, dangerous, and a long shot at best. He was to accelerate toward this oncoming alien vessel and lay down a spread of missiles and kinetic-kill projectiles in the hopes of disabling it. There was no question of matching course and speed with the thing, not when it was burning its way across the system at a hair under c. But Concord would still have to get uncomfortably close, and loosing that much kinetic energy and flying debris when you just might fly into the high-velocity cloud yourself was not Dahlquist’s idea of a reasonable request.
There was the political angle to consider, too.
If the Concord openly helped the America—and from the data feed Dahlquist was getting, these orders were part of a USNA operation against unknown aliens working with the Confederation—he could technically be committing treason.
Damn it, that Prim was putting Dahlquist in an impossible situation!
“Comm,” he said. “Send a reply. Ask for … clarification.”
“Sir, they won’t get the reply for—”
“I know. Send it.”
“Aye, aye, sir.”
Dahlquist had better things to do than jump through hoops held by that perverted little Prim …
