This is an excellent book, plain and simple. It is straightforward and explanatory, told from the point of view of a small child entering school for the first time. The teacher calls the little boy Max, as the name on the class list doesn’t seem to fit. He doesn’t know which bathroom to use, as the other kids don’t seem to want him visiting either. Even though he makes friends easily, all the other kids keep asking if he is a boy or a girl. The word “transgender” is introduced on the first page, and we are walked through exactly what that means. A stellar choice for children of all ages.
