American Vampire – Jennifer Armintrout

Graf's stuck in a town where no-one enters. . . and no-one leaves.
As a vampire Graf's free to indulge his every dark, dangerous and debauched whim. He was just looking for a good party, until a road-trip detour trapped him in the cursed town of Penance. The eerie community affects Graf in ways he never expected and he soon finds himself going against his very nature to protect town outcast Jessa from a sinister attack.

Keeping her safe is a surprising impulse, yet working with the human girl could be Graf's only hope of breaking the spell that binds the town. That is, if he can keep his lethal urges and deadly desires under control.
