A dangerous new magic swells across the land...

Tamri is finally free of the oath bond and apprenticed to the Fire Queen. Their first task: figure out how to seal up the newly unleashed Lightning. The treacherous substance is spreading, affecting the dragons, the Wielders, and Tamri herself-not that she'll admit it.

With unfinished business back home, Tamri travels to Pendark to rescue her grandmother. But she'll get more than she bargained for when she faces her captor, who wants the Lightning for himself. Saving Gramma Teall could condemn the rest of the continent.

Meanwhile, vicious thunderbirds attack the mainland. Someone is using Lightning to control the magical creatures. Tamri must discover their identity before everyone she loves perishes beneath the swarm.

This special edition hardcover features exclusive bonus content, including new drawings of Heath and Gramma Teall, a second cover under the jacket, and journal entries by Latch Brach!
