Barley thought he had escaped the clutches of the Dragon of the Deep. . . But now, it seems that Barley is being turned into a dragon again. Desperate to stop the transformation before it's complete, Barley races to Wizard's Keep for help. At Wizard's Keep, Rye struggles with his apprenticeship. Master Thornberry is patient and kind, but how can a poor farm boy keep up with apprentices who can read seven languages or have had a magic tutor since they were three? It's no surprise he's only learned one spell. Neither of them suspect that Master Thornberry's arch rival has sent a thief to Wizard's Keep to steal the last ingredient he needs for his wicked plot to take over the kingdom, a thief that Barley and Rye accidentally let in. Join Barley and Rye on their most action-packed adventure yet as they race across the Emerald Realms to save Barley from a dragon's curse and the Land Far Away from certain doom.
