For fans of the Warriors and the Guardians of Ga'Hoole series comes the action-packed fourth and final book in this first installment of the Guardian Herd series--now in paperback, with a never-before-seen short story that introduces readers to a whole new world.

After many moons of constant struggle, Star must face his toughest, deadliest challenge yet. Nightwing the Destroyer has captured all the pegasi of Anok, including Star's friends. And when Star learns of Nightwing's merciless plan for the captured herd, he knows the time has come to fight.

With his enemy Frostfire now as his only ally, Star searches Anok with Frostfire to track down Nightwing. And as a violent storm approaches, Star and Nightwing face off amid quaking lands, dangerous winds, and blazing fires, in a battle to end all battles--and one that will determine the fate of all the pegasi in Anok.
