Tender Master (2018)

Caleb knew he was from a special race born to serve the Crystalline gods. Monks trained him as a priest until he reached adulthood, and then he went to Crystalline palace to serve his masters-as a sex slave. Caleb's world is shattered. His beloved gods are lascivious pigs. He can't accept that the righteous faith he built his whole life around is a farce. Caleb flees the god's harem to try to be a missionary for them. He hopes putting some distance between him and his new duties will somehow bring back the ideals he had growing up. Unfortunately for Caleb the Crystalline gods aren't the only ones who desire his kind. General Cain, a high-ranking demon for the Crystalline gods' worst enemy, is looking for a mate just like Caleb. When his ship is destroyed he's marooned on an icy world with his new demon suitor.
