Jade is a seventeen-year-old mixed martial arts fighter. When she’s in the cage she dominates her opponents—but in real life she’s out of control.

Hoping to discover herself, she instead uncovers a shocking conspiracy. In a world just beyond our own, a man is stealing the souls of children to try and live forever.
