One of the Boys by Victoria Zeller

I came across this book by way of an It Could Happen Here interview: https://www.iheart.com/podcast/105-it-could-happen-here-30717896/episode/trans-fiction-trans-sports-275232665/

Properly a tale of a trans teen girl trying to sort her life out, learning the value of community and that all her friends also have messy lives. The hook is that a trans girl rejoins her old football team and needs to balance her old life with her new identity and friends. Lots of highs and lows.

Recommended!
