Fallen Angels (Nicholls)

Sold into slavery when he was six years old, Kai has never known love. As he reached maturity, his slavers realized Kai was no ordinary man. There was something else lurking inside. An uncontrollable force that feeds on his rage and anger gives him the advantage when thrown into the pits of Darkmide to fight for his life. There he learns that killing brings rewards - after each win, he's given a female slave to sate his sexual needs.

Jana, a powerful witch, and Tigan, a deceitful mercenary from Sabe's and Kiera's past, join forces to summon Samyaza, one of the most powerful of all fallen angels. The witch strikes a bargain with the fallen angel to possess Tigan, making him indestructible in battle. In exchange for granting this gift, Samyaza seeks a sacrifice, someone gifted with seraph abilities so he can free himself of the bonds that hold him captive in hell.

The story continues from book two, Angel Within, where we left Eloise in a state of unrest at Kai's disappearance. Can Eloise save Kai? If she does, is he going to be the same man she fell in love with? Or will he revert to his old persona? Confused by overwhelming emotions of despair and betrayal over losing her lover, Eloise finds inner strength and rages with determined purpose to aid her husband's return. Together with her comrades and the angel Anael, she makes her plan to rescue Kai, but as always when dealing with angels, it is not so easy.
