This was a really fun, energetic read. And the mystery had me hooked. I love John Green's writing, even if I don't think there are any teenagers in the world that really talk like that. :D 
 Anyways, I loved this and devoured it in just two days. I particularly loved the friendship dynamic - Q's highschool friend group made me miss mine a little bit. And his feelings about leaving high school hit me hard since I just went through that myself last year. 
 All in all, I recommend this. It's not TFIOS, but it's delightful anyways.
