Jael Thompson has never really fit in. She’s changed schools too many times to count. The only family she’s ever known is her father, a bitter ex-priest who never lets her date and insists she attend the strictest Catholic school in Seattle. And her mother—well, she was a five thousand year old demon. That doesn’t exactly help.

But on her sixteenth birthday, her father gives her a present that brings about some unexpected changes. Some of the changes, like strange and wonderful powers and the cute skater boy with a knack for science, are awesome. But others, like the homicidal demon seeking revenge on her family? Not so much.

Steeped in mythology, this is an epic tale of a heroine who balances old world with new, science with magic, and the terrifying depths of the underworld with the ordinary halls of high school.
