Mim, Gym, and June — Denis Roche

Mim is small for her age, and that's just fine with her. She can fit in places where other cats can't and her school principal always remembers her name. Best of all, she always gets to be first when her class lines up. But everything changes when she meets June in gym.
June makes life miserable for Mim, and that's even before they wrestle. . . . Only the unlikeliest of events can make things right between these two very different cats.
