When mechanical genius Emily is kidnapped by rogue automatons, Finley Jayne and her fellow misfits fear the worst. What's left of their archenemy, The Machinist, hungers to be resurrected, and Emily must transplant his consciousness into one of his automatons – or forfeit her friends' lives. With Griffin being tormented by the Aether, Finley turns to Jack Dandy, but trusting the master criminal is as dangerous as controlling her dark side. When Jack kisses her, Finley must finally face her true feelings for him…and for Griffin. To save those she cares about, Emily confronts The Machinist's ultimate creation – an automaton more human than machine. Can Emily summon the strength she needs to gain her chance at triumph?
