The ultimate showdown of wills has arrived: it is Calvin against the babysitter. In this classic collection, the rambunctious six-year-old finds himself locked in an epic struggle for power with his dreaded nemesis, Rosalyn. Armed with his stuffed tiger Hobbes and his superhero alter-ego Stupendous Man, Calvin is determined to avoid bedtime at all costs. But Rosalyn is no ordinary babysitter, and she is more than ready to fight back. When he is not trying to overthrow the babysitter regime, Calvin is busy avoiding homework, crashing into things with his wagon, and plotting in his top-secret treehouse. Readers will enjoy watching the early iterations of Calvinball take shape and witnessing the chaotic results of a family camping trip gone wrong. Whether he is daydreaming about dinosaurs in the middle of math class or fleeing from mutant snowmen, Calvin proves that life is an incredible adventure. This collection beautifully balances the hilarious frustrations of childhood with a touching look at the limitless boundaries of a kid's imagination.
