A young girl is born the heir to an alien religious dynasty. Possessing the power to destroy worlds with her mind, Liana is under an assassination order from the government of her father's home world. A foiled coup attempt results in a power vacuum that leaves the alien world without its treasure weapon. The aliens have no choice but to take Liana as their reluctant new Avatar. Only an angry slave and a small group of resistance fighters can free her—and the universe—from the dangers of her power.
