Sunshine in Hades

^{Cerberus, a coliseum gladiator, has been ordered to become a stud for breeding a new generation of powerful warriors. For political reasons, Phaethon, a handsome priest of the sun god, has agreed to give the virgin gladiator lessons in sex. At first, Phaethon underestimates the reserved Cerberus, but the gladiator’s eyes hold a smoldering love that borders on raging inferno. Can the love between two lonely souls break the chains of social status that bind them?}
