From the acclaimed author of the Earthseed series, two immortals chase each other across continents and centuries, binding their fates together—and changing the destiny of the human race. 

In the far future, the human race is divided into two groups striving for power. The Patternmaster rules over all, the leader of the telepathic Patternist race whose thoughts can destroy or heal at his whim. The only threat to his power are the Clayarks, mutant humans who live either enslaved by the Patternists or in the wild. 
  
Coransee, son of the ruling Patternmaster, wants the throne and will stop at nothing to get it, even if it means venturing into the wild mutant-infested hills to destroy a young apprentice—his equal and his brother.
