This book is stunning. It tells the story of Riley, a gender fluid teenager dealing with life and the consequences of being different. It's beautifully written and forced me to look at myself with new eyes when I found myself straining to assign Riley to a category: I wanted to know if Riley was born male or female. But that's not the point. Riley is gender fluid, so it doesn't matter what parts they were born with. I loved this story, I loved how real it felt, I loved the way it was written, and I loved the conversations that sprang up as I discussed it with my coworkers and friends while I was reading it. I cannot recommend this book highly enough.
