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.
