I'm trying to think what other book I read recently that dealt with Asperger's and I couldn't STAND IT! Meanwhile, this book, where the main character also has Aperger's, was so much more intriguing, genuine, and I loved reading this book with her in it! And Stanley too, he was also great. Need a teen book that deals with mental health? This one. Rare bone diseases? This one. Zoos and treating animals humanely? This book. Unhealthy relationships and abusive parents? This book.

Spoiler

Homelessness? This book. Sex for first timers with constant and enthusiastic consent? This book. The first time I've ever seen a YA book with a blow job in it?
This book!

Obviously it's for older teens as Alvie is 17 and is attempting to become legally emancipated, but it covers so many topics in such a good way I think any mature teen could read it.
