Seahaven - The Ravencrest Chronicles, #1

Gareth Vann is an renowned thief in the city of Seahaven. The rugged scoundrel is mostly concerned with coin and drink, but has an altruistic streak he tries to hide. He never intended to be a hero, but when Gareth becomes the target of a pair of vampires, he finds himself trapped in the middle of a conspiracy that reaches all the way to Castle Ravencrest itself. To protect those he cares most about, Gareth must reluctantly hunt the creatures of the night the only way he knows how: From the shadows.
