This is a must-read for anyone interested in keeping up with influential YA books. It feels almost like a spiritual successor to the likes of Aristotle & Dante Discover The Secrets Of The Universe in capturing that feeling of in-between-ness and having another person in your life help you learn how to be you. It's the sort of book that sticks with you for a while. This book also has perhaps the single best portrayal of depression that I've seen in a YA book. It's incredibly common in YA to have "mental illness rep" written by someone who is only interested in paying lip service and garnering interest from people who want to see protagonists who they can relate to--and usually they just wind up being pretty offensive. I've even seen it in cases where it's a condition that the author suffers from themselves where it still comes across as patronizing. This was not that. Although the protagonist is a very different person from me, he managed to be incredibly relatable and I felt as though my severely depressed teenage self finally had some good representation.
