Terrible. As a mother of a transmasculine son, I wouldn't put this thing within 100 feet of him or any other children. It's bigotry and right-wing brainwashing at its finest- what does this author have against children who feel they are uncomfortable in their own bodies and seek to change that feeling to happiness? Imagine if you were turned into the opposite sex. It would feel awful, wrong, like you were not the right person. I highly suggest that instead of buying this book, parents, you take a good long look at the society we live in and seriously think about letting your child be free and human instead of forcing them into a little box that you deem the normal human state.
