Witch hunts are on the rise and supernatural turf wars are reaching a boiling point. Then, just when it seems life couldn't get any worse for Pete, Jack reappears-but he's no longer the man she's always known. Hell has changed him forever. And he's brought back with him a whole world of trouble... A cabal of necromancers are using ancient, unspeakable magic to turn the tide of war in their favor. Then, as the city is about to sink into chaos, Pete receives a chilling directive: To end the war, you must kill the crow-mage. Beset from all sides, Pete finds herself turning to an unholy source for help...even if doing so could destroy Black London-and life as she knew it-once and for all.
