A voice in the wind sings on . . .Shard is a gryfon entrusted with a great responsibility. A dragon of the Sunland has left her newborn kit to his care, and now Shard has difficult decisions to make about how best to keep the swiftly growing dragonet safe, while remaining true to his own destiny and the prophecy of the Summer King. He sets out to return the dragonet to his kin in the Sunland and find help for his own quest, but his hope for making wise and benevolent allies is quickly replaced with the reality of cold, mistrustful dragons who want nothing to do with gryfons, Shard, or his wars in warmer lands.

In the Silver Isles, the warrior gryfon Caj sets out on a dangerous hunt for his mad wingbrother, Sverin, once the mighty Red King. The safety of the pride, and in the end, Caj's life, may depend on his success or failure.Meanwhile, Shard's wingbrother Kjorn seeks to find him and reconcile, and his quest will take him across the land that was once his birthright and into the heart of tricky alliances, enmities, and the ever-looming threat of the Voiceless, fear-mongering wyrms.

The Song of the Summer King promises that one will rise higher, one will see farther, and his wing beats will part the storm . . . but as Shard learns more of the world and the tangled threads of fate, he begins to fear that no one can part the storm of growing hatred and fear--not even a Summer King.
