The text in Caldecott medalist Peggy Rathman’s latest book tells a simple story. Father begins counting down to bedtime, and his son does his best to get ready. He takes his bath, puts on his pj’s, and brushes his teeth. But this is not a typical evening. The boy’s computer-literate hamster has created a Web site that invites virtually every hamster on the planet to come take a “bedtime tour” of the house. As more and more hamsters arrive, the boy’s nightly bedtime ritual turns into a fun-filled circus.
