I feel like I need to explain why I've put this on my "will-not-read" shelf. 
 Now, I have listened to people who are chronically ill and I have read reviews and thoughts on certain ableist tropes, which are unfortunately featured in this book, specifically the ending. 
 I've decided I'm not going to give this a read but I have heard that Yoon's other book "The Sun is Also a Star" is a much better book and beautifully written. 
 For more info on why I'm not going to read this or even see the movie when it comes out, read this review here and this blog post here
