Hers To Command by Cynthia Sax
Three Battered Hearts. One Perfect Love.
Ace and Thrasher share a special bond. They’ve never acknowledged that connection and have never fully acted on it. The Humanoid Alliance kill cyborg males like them, deeming the warriors to be defective. Now that Ace and Thrasher have escaped, they don’t trust the cyborg council and their brethren to react any differently. Physical love is too risky for them to consider.
Until they meet her.
Carys is the Commander of a Rebel Battle Station. She has dedicated her lifespan to seeking vengeance against the Humanoid Alliance and the cyborgs who killed her daughter. On her battle station, she makes the rules, and if she wants to kiss, touch, and pleasure two mysterious warriors, she will. Nothing, not even enemy warships and a mass cyborg rebellion, can stop her.
In the midst of a war, enemies can become lovers and loyalties can change in a moment. Can a forbidden relationship between two cautious cyborgs and one unbending human Commander survive?
