These sons, each gifted in the arts of war, grow up and seek to destroy the men who killed their father. But sibling rivalry and jealousy are more dangerous than the battlefield. The youngest brother, a delicate beauty in the bedroom and a demon on the battlefield is particularly vulnerable. Will he ever find comfort and love, and with who?
