There is no way I can write a review that will do this book any justice.
It is beautifully written, with characters you will fall in love with. And it does a great job describing what it's like living with autism or depression/anxiety.
I would recommend this book to everyone. Even if MM isn't your thing, that is so not what this book is about. The main characters just happen to both be male. It is all about love, learning how to live with a disability and that there is no such thing as "normal".
So do yourself a favor and read it, you won't regret it!
