Power corrupts. Magic kills. Eighteen-year-old Jemmie Carmichael is surrounded by magic in the quiet town of Hawthorne, New York. In her world, magic users are called “kindled,” and Jemmie would count herself among them if only she could cast a simple spell without completely falling apart. It doesn't help that she was also recently snubbed by Crowe—the dangerous and enigmatic leader of Hawthorne’s kindled motorcycle gang, the Devils’ League. When the entire kindled community rolls into Hawthorne for an annual festival, a rumor spreads that someone is practicing forbidden magic. Then people start to go missing. With threats closing in from every side, no one can be trusted. Jemmie and Crowe will have to put aside their tumultuous history to find their loved ones, and the only thing that might save them is the very flaw that keeps Jemmie from fully harnessing her magic. For all her years of feeling useless, Jemmie may just be the most powerful kindled of all.
