Thanks to NetGalley and Random House Children's for an advance copy!

tl;dr
A thoughtful and complex story featuring a likable non-binary protagonist and a great supporting cast. The amount of prejudice the MC has to face is really stressful to read.

About
Only girls do magic. Only boys can be knights. Callie has never thought of themselves as a girl or a boy, but their dream to become a knight someday is blocked by the fact that everyone else sees Callie as a girl. But Callie's determined to prove themselves, and an invitation to the royal capital might be the chance they need to do so.

Thoughts
This is a tough one to review. I typically try to highlight things I enjoyed versus parts that weren't for me, but it was hard for me to enjoy this. To be clear, this is a very good book. Callie's struggles are raw and relatable, and my heart broke for them more than once. The other kids are unique and complex and beautiful, and it was great to see genuine thoughtfulness centered on the discussion of family and abuse, self-loathing, and how messy love can be. But dang, reading this was tough. Callie is misgendered regularly, on purpose, and with hurtful intent. Gender roles in this world are so rigid and pithy that even our heroic Callie starts out with a very dim view of women. Trans readers who have been down this path in real life already might find re-treading this ground to be tiresome. That being said, I think this book would have been perfect for me when I was younger, and I think it will resonate with any young reader looking for a story about friends, family, and adventure.
