Skyfire

The second book in the Summer King Chronicles, by Jess E. Owen.

Shard is a gryfon in exile from the pride of the Silver Isles. After learning of the injustices wrought by the Red King he once served loyally, Shard now seeks to fulfill the promise of the legendary Summer King, who is destined to bring peace and balance when he appears.

There he will learn of the fierce enmity that drove the Red King and his pride from their homeland, and the deadly grudge stretching back two generations that, if left unfinished, could destroy them all...
