The next season of the show is going to cover this book and man, I'm about to be an emotional mess. I honestly can't wait to see how they deal with it in the show, and praise Alice Oseman for her ability to write something heavy without it feeling too heavy.

As the most recent addition, this is obviously the volume I've read the least, but the way that Oseman deals with mental illness in this book is just so important. Especially since we get to see it from both Nick and Charlie's perspectives. Charlie is afraid to get help because he thinks that his parents won't believe him. It's hard asking for help, for anyone, but I think especially for teens. Nick's support in Charlie getting the help he needs is such a crucial depiction in YA literature.

Nick really wants to help Charlie but doesn't really know how. His conversation with his mom about figuring out the best ways forward is such an important conversation to have in light of mental illness. Because Nick can't cure Charlie, but he can be there to support him every step of the way. I could keep going about how much I love this representation, but I'll stop there. And I absolutely cannot wait to see this adapted on screen.

I read this too quickly, but I'm not even sorry about it. Oseman deals with mental health gracefully. There are some great conversations about it here. I already want to read it again.
