"Set in the world of Buffy the Vampire Slayer, the first book in this series will introduce our new slayer as she grapples with incredible power she is just beginning to understand"--

Nina and her twin sister, Artemis, grew up at the Watcher's Academy, where teens are trained as guides for Slayers-- girls gifted with supernatural strength to fight the forces of darkness. While their mother is a prominent member of the Watcher's Council, Nina has never embraced the violent Watcher lifestyle. Instead she follows her instincts to heal, carving out a place for herself as the school medic. Until her life changes-- and now Nina is not only the newest Chosen One-- she's the last Slayer, ever. Period. She's honing her skills on a monster fighting ring, a demon who eats happiness, a shadowy figure that keeps popping up in Nina's dreams... and then the bodies start turning up.... -- adapted from jacket
