Varian, leader of the Na'Chi, a hybrid race of gifted warriors, is cursed with the darker impulses of his demon heritage. Controlling the part of himself that craves the high of the battle is a struggle he's afraid he'll lose--until he meets Kymora Tayn, a priestess driven to serve her deity. While he's unwilling to trust anyone outside his people, he finds himself drawn to Kymora's strength and passionate nature, and discovers she has the power to calm the darkness inside him.
When the Na'Reish raid human territory for blood-slaves and kickstart the war, the key to the survival of both races--Na'Chi and human--is an alliance. However when Kymora is kidnapped, pitting human against human, Varian realizes he must embrace his darker half, not only to save the alliance...but also the woman he loves.
