Hermes. Frozen Origins, #2

Hermes was a god, one of the line of genetically manipulated super beings. He was a mix of human and alien, and they had just been freed from Origin, the company that had created and enslaved them. Sent on a mission, he was captured by a rogue agent of Origin who was intent on auctioning him off to the highest bidder. He hides Hermes at his father's estate where Cherish, the agent's sister, sees him and becomes infatuated.
She makes sure he's fed and he comes to care for her. Is she his mate and does it even matter since he can't escape? Will she help him and what will happen if she does? Attraction flares between them, will love follow?
