Lynne Jonell, the popular author of Emmy and the Incredible Shrinking Rat, makes her Stepping Stones debut with a laugh-out-loud funny story of wayward wishes and mixed-up magic.

Celia Willow is the baby of the family, and she's sick of it - sick of being younger and smaller, and sick of never being taken seriously. So when Hammy, her hamster, magically starts talking and then offers to grant her a wish, Celia impulsively shouts one out. She wishes to be big. But Celia's wish doesn't turn out quite the way she wanted. Instead of being a big person, Celia becomes a big hamster. She wants to run all night and gnaw on things and make cozy burrows. Can her older brothers and sister, Abner, Derek, and Tate, figure out how to return Celia to normal . . . before their parents discover their daughter is a dog-sized furry rodent?
