Books like crown of shadows

Crown of Shadows is a fantasy novel by American writer C.S. Friedman, first published in 1995. It is part of the Coldfire Trilogy.

Damien and Tarrant return to the west and Jaggonath, where they agree to work together long enough to kill Calesta. Damien discovers that the Patriarch of the Church, who is firmly against sorcery, is actually an Adept himself. Tarrant further strains relations with the Unnamed by revealing this fact to the Patriarch, and is dragged off to Hell for his pains. Damien convinces another Iezu, Karril, to lead him through Tarrant's personal Hell to the Unnamed, where he bargains for the Adept's life. The Unnamed agrees, on the condition that its contract with Tarrant will be broken in thirty-one days. If the Hunter has not found another way to sustain his immortal life by then, he will die. The Patriarch, already displeased at Damien's saving Tarrant for the first time in the Rakhlands, comes extremely close to casting him out of the priesthood. In the end, however, it is Damien who chooses to no longer be a priest, because his faith has been questioned too much by the Hunter, by himself, even by the Patriarch. Gerald Tarrant, on the other hand, has found a way to destroy an Iezu: feed it with the opposite emotion it normally thrives on. Karril, who lives off Pleasure, can also accept Pain, but Apathy will destroy him. Calesta, who embodies sadism, can only be destroyed by Altruism- the ultimate sacrifice, which Tarrant, amazingly, is willing to pay.
