Tam Gu: Curse of the Wicked Warlock, (Paperback)

It's been 5 years since the four friends completed the Tam Gu and saved the world. In this story, they are reunited with their special mentor in the alternate universe of Azorith. This time, Saja needs their help breaking an evil spell cast over both their universes by the Wicked Warlock. The kids must complete a series of tasks to gain access to the castle of the wicked warlock where they must battle him for the fate of all mankind (and alien-kind, alike). Will the kids make it through the trials in order to earn the Ring of Unity? And how will they overcome the monstrous creatures of Azorith.
