When Mac, Masie, Bird, and Pokey find mysterious tokens in their cereal boxes, they're transported to Cardboardia, a magical land made of paper and cardboard. In this parallel universe to ours, creativity thrives. Every time a box of anything is created in our world, a replica appears there, bringing residents art supplies, food, books, and more. But an evil presence is slowly moving in, threatening to wipe all art and beauty from this paper paradise. It's no mistake that the four friends have been transported through their cardboard portals. Each has a special talent they never knew existed. And only when they figure out to harness them together will they be able to stop the destruction. -- Adapted from book jacket flap and information provided by publisher.
