I read a lot of John Green's books when I was in high school. I am not sure why I never picked up this title, but I am glad that I eventually got around to reading it. Turtles All the Way Down is a complex story. Aza, the main character, lives with mental illness (I don't want to do the whole armchair psychologist thing and diagnose her officially, so I will just say she definitely has OCD and general anxious tendencies). As someone who lives with anxiety, I saw myself in this book. No, I do not have the same fears as Aza, but the way those fears overwhelm her and those around her was relatable. A warning to those who read this title: make sure you are somewhere you feel comfortable when you read the end of this book. And buy lots of tissues. You will need them.
