Running from the Cyborg by Anne Kane
Caitlyn: Gorgeous. Feisty. Human. A survivor in an unforgiving galaxy. Running from an enemy she can’t see for reasons she doesn’t understand. Whoever he is, he’s trying to kill her.
Jakob: Large. Mouthwateringly sexy. Loyal. Cyborg. Determined to find the female who seduced him, gave him a night he’d never forget, then disappeared before he woke. When he finally manages to catch up to her, he intends to do whatever it takes to keep her at his side.
