Headstrong young witch Savannah Levine is in terrible danger when, having sworn to give up her spells if it would help a young girl caught in a horrible bind, she finds herself without her powers and with a witch-hunter out to kill her. Isolated from those who can protect her and unable to use her vast spell-casting talent, Savannah is forced to rely on mundane skills and her half-demon best friend, Adam, to turn the tables on her would-be killer and recover her magic.
