In this joyful and impactful picture book， a transgender boy prepares for the first day of school and introduces himself to his family and friends for the first time。

Calvin has always been a boy， even if the world sees him as a girl。 He knows who he is in his heart and in his mind but he hasn't yet told his family。 Finally， he can wait no longer: I'm not a girl， he tells his family。 I'm a boy--a boy in my heart and in my brain。 Quick to support him， his loving family takes Calvin shopping for the swim trunks he's always wanted and back-to-school clothes and a new haircut that helps him look and feel like the boy he's always known himself to be。 As the first day of school approaches， he's nervous and the what-ifs gather up inside him。 But as his friends and teachers rally around him and he tells them his name， all his what-ifs begin to melt away。

Inspired by the authors' own transgender child and accompanied by warm and triumphant illustrations， this authentic and personal text promotes kindness and empathy， offering a poignant and inclusive back-to-school message: all should feel safe， respected， and welcomed。
