One morning, Meerin Hoy looks out her window to Carson's Field. There to her shock stand two big development signs - for sure spelling the end to her community's most beloved park. But nine-year-old Meerin is no ordinary girl. She is determined to act. But when she confronts the mayor in person who dismisses her as "just a kid," it's time for Meerin to take on the tools of a local activist and save an important community asset from the powers that be. Just a Kid is a reflection of movements that are occurring in many parts of the world today - some of them inspired by the advocacy of Greta Thunberg, the students of Parkland in Florida, and many others. For that reason, but also because this is a winningly told story, Just a Kid is a timely novel for young readers to learn about the possibilities of influencing the adult world, even when it seems no one wants to listen.
