Saved By the Cyborg by Jessica Coulter Smith

Intimidating. Damaged. Unlovable.

Tark wanted a mate even before he joined the Cy-Con program. His sheer size made females fear him, and now that he’s been turned into a cybernetic freak they avoid him even more. When he finds a female being held in a brothel against her will, he knows that he can’t leave without her.
Tark means to take Suki home to his world, a place where she can heal and start a new life. He never realized she’d want to start that life with him, or that she’d insist on leaving the safety of Xpashta in an effort to rescue others like herself.

Brave. Fearless. Pregnant?
Tark saved the alluring human female once. When she’s captured during a dangerous mission, he knows he’ll have to do it again, and this time, he’s not letting her out of his sight — especially when he finds out she’s pregnant with his child.
