I quite enjoyed this one although it fell a bit flat plot wise.
Aza´'s fights with her OCD was crazy to read, the struggles with her own thoughts are well done and I think they are very well portrayed.
Other then that, we have our classic teenage characters trying to solve a mystery but that is quickly put aside.
To me it felt a bit like the author forgot what the actual story was supposed to be or went off the rails at some point.
I have other John Green books on my shelf and have more hope for those!
