Counsel of the Wicked
by Elizabeth A. Schechter
Matthias has spent his whole life on the edge of a very small world. The bastard child of a fallen woman, he's known nothing but judgment and hatred from the harsh, religious people of his enclave—except for Balthazar. The son and heir of the High Elder, Balthazar shows Matthias kindness, love... and desire. But when the High Elder discovers them, Matthias is sent to a prison called the School.
