Along with Jemma's boyfriend struggles, her friend Kate is tackling a whole separate issue of body image. After a "Fat or Not Fat" slam book goes around the 8th grade class labeling Kate in the "mostly fat" column, she struggles with her perception of her body. Moffitt does a great job of dealing with Kate's body issues, respecting the difficulties that teen girls often have with this issue. She leads Kate to make healthy decisions and be accepting of the body she does have.
Overall, if you liked the first two books in this series, add this one to your reading list. Mothers and daughters this is a great series to read and talk about together!
