TRAPPED IN A STRANGE WORLD!

Sandy and Tim Johnson spend every summer on Mackinac Island... but this year, something goes very wrong! After being swallowed by an old tree, they find themselves trapped in a strange world filled with weird creatures and a curious old miracle-maker. Their only hope is to find the mysterious Stone Key... the key that will return the Isle of Mayhem back into the Isle of Miracles, and open the door that will allow Sandy and Tim to return home.

But in a land filled with dangerous Wartwings and Blinkmongers and other scary creatures, how can they possibly succeed?
