After telling her dog Banana about her loose tooth and discovering that some of her friends do not believe in the Tooth Fairy, Anna makes an impulsive bet with a pesky boy who also has a loose tooth.

Anna has looked forward to her class field trip to the zoo, but from the time they board the bus she is pulled between her long-time best friend, Sadie, and new best friend, Isabel, who argue about everything and want Anna to take sides.

Anna and Sadie have always been best friends so when Sadie suddenly starts being mean, Anna is very sad and seeks support from her dog Banana and classmate Isabel, as well as advice from her brother Chuck and her parents.

Anna’s sure she, Sadie, and Isabel are complete as a trio, and winning the bake sale will prove it. But when Monica shows up with Sadie and Isabel for their big baking day things quickly turn from sweet to sour. Can Anna win back the attention of her two besties, or will she learn that friendship—like cookies—is best when shared?

But magic isn’t as easy as it appears, even with a book of instructions.

With the neighborhood potluck coinciding with Mrs. Shirley’s seventy-sixth birthday, Anna and her friends decide to practice their own magic act to perform for her, but a whole slew of mix-ups ensue as they try to puzzle out how the tricks are done and how to figure out Justin’s secret, too.
