Dark Arsenal by Cynthia Sax

A cyborg warrior and a Rebel female’s first mission together might be their last.
Arsenal considers himself to be a disposable cyborg. He drifts from assignment to assignment, forming no connections to anything or anyone. When the cyborg council requires a warrior for a high-risk mission, Arsenal volunteers. He believes no one will miss him if he dies.
He doesn’t realize he’s one female’s fantasy.
The moment Vicuska glimpses Arsenal’s image, she knows he’s the male she wants to spend her last moments in the universe caressing. The Rebel female craves the cyborg’s grim-lipped kisses, desires the touch of his hands, hears his deep voice in her dreams.
Their mission will end in explosions and death. That is certain if they fail or if they succeed. Whether or not they’ll find love during their dangerous assignment is the unknown.
