It’s Jack’s sixth birthday, and he’s bored. Bored! Model airplanes, stuffed dinosaurs, not even a talking robot can free him of his festering funk. Then, a mysterious box arrives. Within is a think-a-ma-jink, a bizarre contraption that bends the very laws of time and space, with which no idea is too fantastic to be realized. A wild new universe of possibilities beckons. Cotton-candy-breathing dragons! Caramel rivers! Space-traveling hot-air balloons! But as he and his sister Marie engage in a boisterous, shape-shifting struggle, the future of the think-a-ma-jink hangs in the balance. Is Jack doomed to boredom . . . or is he on the verge of an amazing discovery?
