To Serve Two Masters [EPUB ebook] 

Market day is a special time on the island of Ilyria. The goods to be sold are men, men who have learnt to accept their lives of slavery. Rock is one of these captive 'livestock’, his only hope being that the beautiful young stranger, Dorian, will be the one who buys him. Even if he is lucky, Rock knows his life will not be easy. Dorian’s adoptive brother, Carlos, is as cruel as he is handsome and Rock understands that, should he be bought by one, he will be owned by both. Fine homoerotic fiction with lashings of SM!
