Pixie Piper is in 5th grade, and although she loves poetry, she's starting to think that maybe it isn't super cool. While at a Renaissance Fair with her family, a woman gives her a fortune about her life saying that she is a "goose girl" and is destined to rhyme. She is not happy with it. Her mother tells her later that night that they are descendants of Mother Goose. Pixie refuses to believe it, but things start happening that make her think it might be true. This book also deals with changing friendships as puberty begins, as well as a slightly mean girl. There is also a toilet museum for slight potty humor.
