Legends of the Dragonrealm: The Gryphon Mage (The Turning War Book Two)

Nathan Bedlam has managed to free most of the human mages from the Dragon Kings' control, but the struggle against the drake lords has not gone well. With treachery at every turn, Nathan knows that the only hope the rebels have is to seize Penacles, the City of Knowledge. Yet, doing that will require forcing the Gryphon to realize the power within him, a power that may also prove to be the rebellion's downfall.
