Very Important Message for All of Us
Format: Hardcover
Absolutely delightful, oftentimes comical look at what is a very serious situation, collection of memorable metaphors of a memoir. A real page turner. I highly recommend it. There is a subtle recognition of a spiritual nature that we are all born with. Only some of us have the courage to live out the compelling spiritual direction that we come into the world with. Thank you Kyle.

Parents beware!
Format: Hardcover
This books is about a trans child running away from home and it basically teaches children how to do it. Nearly a step by step example. Then at the end of the book the author offers “resources” and advice. The first advice the author gives is “this book itself is the advice” (meaning: run away from home) and then the author lists ways a child can get around their parents. Even telling children that if they have parental control features on their phones preventing them from looking up stuff (assuming “resources” to run away) that they can go to the library, even suggesting they ride their bike to the library so their parents don’t know, to look up “resources” at the library. My daughter was somewhat disturbed by this book. She said: “I feel like it’s trying to brainwash me into hating you! I had to remind myself of who I am like every chapter. I’m afraid for kids who don’t know better.” Parents beware!

Nasty
Format: Hardcover
Terrible blaming parent for trying to protect their child. She is committing a great moral evil. Shame on Dial Books for Young Readers for greenlighting a book with such a false, evil, and vindictive premise.
