Tyrant Moon tells the story of a dying mage who must help a barbarian warrior in her quest to save her people. Thraxis is an Athraskani wizard who created a magic jewel that would gift any mage with enormous power. A rogue wizard stole the jewel, using it to cast a death curse on Thraxis before fleeing to hide among the barbarian tribes. The Arrow that Flies the Farthest is the Champion of her clan-its most skilled warrior, whose ritual combats with other Champions were meant to prevent war among the clans. But war is unleashed nevertheless when her ambitious chieftain joins forces with the rogue Athraskani. Arrow's only hope of stopping the war seems to lie with Thraxis, who alone knows how to destroy the jewel he created. But can a pacifist wizard and a woman born to kill find the common ground needed to work together...before time runs out for them both?
