Waking the Witch (Otherworld #11)
by Kelley Armstrong
At twenty-one, Savannah Levine-orphaned daughter of a notorious dark witch and an equally notorious cutthroat sorcerer-considers herself a full-fledged member of the otherworld. The once rebellious teen has grown into a six-foot-tall, motorcycle-riding jaw-dropper, with an impressive knowledge of and ability to perform spells. The only problem is, she's having a hard time convincing her adoptive parents, Paige and Lucas, to take her seriously as an adult.
Suddenly, Savannah gets the chance she's been waiting for: Recruited by another supernatural detective, she travels to Columbus, Washington, a small, dying town. Two troubled young women have been found in an abandoned warehouse, murdered. Now a third woman's dead, and on closer inspection small details point to darker forces at play. Savannah feels certain she can handle the case, but with signs of supernatural activity appearing at every turn, things quickly become more serious- and far more dangerous-than she realizes.
