Set against the backdrop of a middle school cultural fair, this tenderhearted and funny novel from the author of The Unbeatable Lily Hong stars twelve-year-old Sophie Mu--who discovers the power of defining oneself as she navigates friendship drama, family expectations, and learning about her Hui, her Chinese Muslim identity. Sophie's work on the Chinese booth at last year's Rainbow Fair is a point of pride for her and her parents, even if Sophie and her best friend, Katie, think the whole thing is a little silly. Sophie's family is Hui, Chinese Muslim. The Muslim part is something she doesn't know much about. Her parents prefer to keep it private. So when it gets slipped to an overenthusiastic teacher that Sophie is Muslim, the only Muslim in her class, suddenly Sophie is in charge of debuting a booth representing the Islamic religion she doesn't practice, an assignment she is determined to keep secret from her parents. Having to choose between leaving the Chinese booth or taking on double the workload leaves Sophie feeling conflicted. Why does she have to choose which part of herself to represent? Is it an issue with her or with how the Rainbow Fair is organized? Between juggling both booths, old and new friends, and learning more about her Muslim faith and ancestry, Sophie starts to notice how her working on two booths starts to spark change throughout the student body.

It turns out Sophie isn't the only one at Monroe Middle School whose identity isn't so simply categorized by the Rainbow Fair's limited booths. One thing is for sure, this year's Rainbow Fair won't look anything like it did in the past, and Sophie begins to realize that that might not be a bad thing at all.
