Brenaith had once been a warrior of renown, companion to the King of Artepia. Now he suffered in captivity as a demon's whore, his country overrun by a race his people had not believed existed. Driven to the edge of madness by his tortures, the final blow comes when his master, a demon lord, gifts him as a blood servant to a Shadow Knight, Shaynith-una, a monster of legend that destroys even souls. Brenaith does not expect to survive the bonding by Shaynith-una, who is rumored to hold divine blood and is held in awe by other demons.

But with time he begins to see Shaynith-una as more than the monster he is reputed to be. The knight is a demi-god. Half demon god, half elf, the son of rape and darkness, mind taken and molded by his demonic deity father. And Brenaith's fate and hope are both bound to Shaynith-una for good or for ill.

Can Brenaith break Shaynith-una's conditioning and discover what and who really lies behind the knight's facade...or will darkness always rule?
