Rune Winters is on the run. Ever since the boy she loved, Gideon Sharpe, revealed who she was and delivered her into enemy hands, everyone wants her dead. If Rune hopes to survive, she must ally herself with the cruel and dangerous Cressida Roseblood, who's planning to reinstate a Reign of Witches. Gideon won't allow the Republic to fall to the witches. Every last witch must die, especially Rune Winters. When Rune makes Gideon an offer he can't refuse, the two must pair up again. The feelings he had for Rune aren't as dead as he thought. Now he faces a terrible choice: sacrifice the girl he loves to stop a monster, or let Rune live and watch the world burn.
