Gwen Harrison spent ten years trying to make peace with the cyborgs. Falling for their commander was never part of the treaty. Widowed by the war with the synths and raising two young children alone, Gwen has no interest in risking her heart again. Then JSN42 arrives at the human enclave as the cyborg liaison. He's controlled, formidable, maddeningly attractive, and far too easy to imagine becoming part of the family Gwen thought she'd lost forever. Unfortunately, the attraction is mutual. The danger is too. A fragile ceasefire is finally within reach when sabotage threatens to turn humans and cyborgs against each other again. Gwen and JSN must uncover who wants the alliance destroyed before one hidden enemy reignites the war and destroys their chance at a future together. Gwen fought for peace between their people. Now she may have to fight just as hard for the cyborg who makes her want a second chance at love.
