This book is amazing. The rhymes are a little harsh at times, but the message is entirely what this book is about. We start with a child going to school and all of her classmates are asking what happened to her brother Bill? Where did Bill go?  The classmates have some wild Bill scenarios that include spaceships, baseball, etc. Going into this book blind, I was very happy to find out it wasn’t something sad. Instead. we find out that Bill is now Lily, and anybody who has a problem with it just needs to chill. I loved it. This is so well done, so right to the point. Tt makes what can at times be a tough subject fun. It also states all the ways that Lily is still the exact same person. Lily is Lily with a new name. I loved absolutely everything about this, and it should be a staple in every public and school library!
