There's more to this museum than meets the eye! This is the wonderfully wacky world of celebrated international author-illustrator team Davide Cali and Benjamin Chaud, the duo behind Junior Library Guild selections I Didn't Do My Homework Because . . . , The Truth About My Unbelievable Summer . . . , and A Funny Thing Happened on the Way to School . . . . Notoriously (and delightfully) unreliable narrator Henry is late to a museum where his class is spending the day. But he has a plan: He'll just catch up in one of the exhibits. That's not possible in these halls! With volcanoes erupting, dinosaurs charging, and secret stairwells lurking, reuniting with his classmates becomes a quest of outrageous proportions. Young readers will revel in this entertaining book's over-the-top antics.
