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 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.

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.

Sadie, Isabel, and Anna decide to enter Banana into a puppy parade to raise money for the local animal shelter, but when Sadie and Isabel get really involved, helping to bathe, brush, and get Banana ready for the big day, Anna starts to feel possessive about her dog.

Anna wrestles with a big secret at Isabel’s super-fun sleepover in the seventh book of this “fast-paced, fun, and funny” (Megan McDonald, bestselling author of the Judy Moody series) illustrated chapter book series about the joys and challenges of elementary school friendships. Anna and her friends love having sleepovers. So, when Isabel invites Anna and Sadie to spend the night at her house for the first time Anna can’t wait! Between pranking Isabel’s older sisters, make-your-own pizzas, and truth or dare this is going to be the best night ever. But when one of Isabel’s older sisters’ dares results in Anna breaking a really special vase, everything stops being all fun and games. Isabel’s sisters convince the girls they can hide it from their parents, but after her friends fall asleep, Anna lies on the floor in her sleeping bag, wide awake. At night, with the lights out and everyone else sleeping, Isabel’s house seems different. Unfamiliar. Not like home. Anna misses Banana terribly, and worst of all she feels really guilty keeping what happened a secret. If Anna doesn’t stay at the sleepover, everyone might get mad at her for ruining it, but if she stays and lets the secret slip about the broken vase, everyone might get mad at her for that instead. Anna and her friends share all their secrets, but can they help her with her secret dilemma?

Includes an excerpt from Anna, Banana, and the recipe for disaster.
