Thank you to NetGalley and the publisher Knopf for providing me with a free digital ARC of this book in exchange for an honest review. To start off, if you still have the option to just read this book now without getting approved for it on NetGalley like I did, then do it! 
This book really broke my heart. I get so emotional when I witness parents supporting their trans children (maybe because my parents don't know I'm trans and think I just changed my name for fun idk). The transphobia from their community is brutal, the justifications and mental gymnastics of the parents not hearing and seeing that their child was trans sooner (even when their child knew from a SUPER early age and told them explicitly), and the comments that Greta makes regarding her transness like "'I'm sad. Why didn't you let me transition earlier?'" or "'Nobody in this town understands what transgender is. So I don't want to be transgender anymore. But I can't be a boy, so I don't want to exist.'" HEARTBREAKING. You can tell while reading this that the mom regrets so much in how she first reacted to her child's trans identity, since she started off denying it or thinking it was a "phase," and you know what, she had a huge learning curve. The way she grows to support and advocate for her child just gave me hope that there are parents like this in the world. I'm so happy that the switch flipped in her head to take her child seriously and believe her. The way the author connected her present situations with her daughter to her gay brother's past was also seamlessly done in my opinion and really shows the author's growth in knowing now how she could have supported both of them better throughout her life. 
The parts where the mom was desperately trying to get accommodations for her autistic daughter reminded me a lot of my mom trying to get accommodations for my brother with ADHD in our rural farm town middle school because they did NOT want to make education more accessible for him. My mom turned to her friend who had struggled hard to get accommodations for her neurodivergent children and she was able to give my mom tips, and this accommodation grapevine is so important in these situations. 
I just felt very emotional reading this altogether, but if you can make it through the difficult read, it is so worth it. Protecting trans kids is more important now than ever, and this book truly exemplifies that.
