Pepper Ann Pearson loves two things with all her heart: Her little sister Moose, and being a girl. After all, what kind of feminist would she be if she didn’t think girls were the greatest?

But after Moose confesses that she wants to become a boy, Pepper Ann finds herself wondering if she can support her sibling and still be a good feminist. And what the heck does “transgender” mean?

Luckily, Pepper Ann has some great friends — along with an annoyingly vocal conscience — to set her on the right path.

Contains depictions of gender dysphoria and transphobia.
