Paladin by Anna Hackett

A cyborg drowning in emotions and an abducted Earth woman trying not to feel.

Abducted, enslaved, and constantly worried for her daughter, scientist Dr. Simone Li has had a rough few months. Now that she and her daughter, Grace, have been rescued by the fierce cyborgs of the House of Rone, she’s trying to make a life for them on the desert world of Carthago. But guilt and worry are eating at her…Toren—a once-emotionless cyborg—was injured rescuing them from the dangerous Edull aliens. Now, he’s inundated with emotions and not coping. Drawn to the wounded cyborg, Simone must find a way to help him and still protect her battered heart.

Bred to be a warlord’s personal cyborg, Toren has prided himself on being a cool, precise fighter dedicated to his house and imperator. Now his entire life has been torn apart. He’s broken, useless, and sidelined as an elite House of Rone cyborg. Every minute of every day, he struggles through a deluge of unfamiliar emotions and wants revenge…and only one woman calms the storm.

Desperate to bring down the Edull and rescue another abducted woman, Toren and Simone go undercover in the desert. Despite the dangers around them, these two tortured souls can no longer fight their intense attraction and the pull of fierce, overwhelming emotion. But Toren will soon have a choice to make: risk it all for love or go back to being the emotionless warrior he’s always been.
