Bloodbound

Larsa is a dhampir-half vampire, half human. In the gritty streets and haunted moors of gothic Ustalav, she's an agent for the royal spymaster, keeping peace between the capital's secret vampire population and its huddled human masses. Yet when a noblewoman's entire house is massacred by vampiric invaders, Larsa is drawn into a deadly game of cat-and-mouse that will reveal far more about her own heritage than she ever wanted to know.
From Pathfinder co-creator and noted game designer F. Wesley Schneider comes Bloodbound, a dark fantasy adventure of murder, intrigue, and secrets best left buried, set in the award-winning world of the Pathfinder Role Playing Game.
