I received this free from the publisher as a banned book but with no request to review the book. 
I liked this book a lot. It has the feel of a book that I would have loved reading when I was young. It is a ghost story, a story about grieving one's uncle, and about gender discovery and the stresses of moving into middle school. It's also a hopeful book which dreams of a world where kids are supported by those around them and can use the bathroom without fear of being harassed. 

My grown daughter read the book and found the scene where Bug's friends try to get (them) to wear makeup to be highly accurate and found similar events in her childhood to be distressing. Surprise, both cis girls and trans boys can be irritated by the same attempts to police their gender expression. This daughter did not share other experiences, like feeling that mirrors were strange and upsetting. I feel that this is all a waste of breath as support for gender nonconforming kids typically comes up only in opposition to trans folk, and evaporates as soon as that's not being discussed.
