Windborn (The Guardian Herd, Bk. 4)

It has been many moons since Star received his powers, and in that time, he and his friends have been through constant struggle. Now Nightwing the Destroyer has captured all the pegasi of Anok, and when Star learns of Nightwing's deadly plan, he knows the time has come to fight. With no one to turn to but his enemy Frostfire, both pegasi search Anok to track down Nightwing. And when they find him, Star and Nightwing face off amid quaking lands, dangerous winds, and blazing fires in a battle to end all battles - one that will determine the fate of all the pegasi in Anok.
