Breathing Vapor by Cynthia Sax
Vapor is the most advanced cyborg the Humanoid Alliance has ever developed. He’s a finely honed weapon, a warrior without parallel, half man and half machine. No lock can contain him. No being can stop him. Whatever he wants, he takes.
He wants Mira Breazeal, the Designer’s daughter.
She’s his one temptation, his sexy target. Vapor shouldn’t crave her caresses, steal her kisses, make her scream with ecstasy. The cyborgs want her dead and they would question his loyalty if he didn’t kill her. The humans would shoot him on sight if he dared to touch her.
Their love is forbidden. Their desire could be lethal. One human and one cyborg will risk everything for a moment of passion.
