Tessa Conley isn't ready to go back home to Austin when her summer course in London comes to an end. She gets her wish as she steps into a new world of urban fantasy and mystery when she is transformed into a living gargoyle, complete with wings and a tail. Mostly human by day and gargoyle by night, Tessa is not alone in her new world with other gargoyles in the bookstore she now calls home. Bree, her best friend from Austin, is kidnapped and held in the UK. Tessa uncovers the mystery of her birthright, and learns what kind of monster she's become in order to save her friend... if she can survive the horror her new life holds in store.
