Thirty years ago, Johnson Frost was just a kid from the Real who got lost and ended up in the Fantasy, where he was to meet his destiny by saving the Wonderland 31. When it was time to go home, however, Johnson refused, hiding in the mountains where he helped the Yetis battle the Nutcracker Army for control of Wonderland. Eventually defeated and exiled back into our world, the once wide-eyed kid grew into a bitter adult with dreams of making himself king!
In the present, a new generation of kids visit Wonderland 31. Farm the Half-Wolverine, Aurora the Fox, Jasper the Porcupine, Flake the Rabbit, and Notter the Otter find the entrance while exploring abandoned miner's tunnels inside the Western Mountain. They encounter a world of Nutcrackers and Yetis, of Marshmallow Bogs and Gingerbread Castles, and learn that Frost is coming back to conquer Wonderland with his Army of Invasives!
It's up to the Five to stop him. Ignored by their parents and the Meadow's Elders Council, the Five embark on the most dangerous adventure of their young lives to save both their home and a world they only just discovered!
