My first John Green book in many many years. I found the way he described Aza’s OCD to be fascinating and offered a lot of insight for me. I also loved the relationship between Aza and Daisy! However, I thought the plot was a bit weak - I don’t think the murder-mystery added anything to the story. It just as well could have been about two childhood friends reconnecting. Also: there was no need for a romance to happen between Aza and Davis. Again, could have just been a story about childhood friends reconnecting.
