4.5 John Green’s depiction of anxiety is flawless. I identified with Aza through so much of the book. Also Green’s world building, for lack of a better word, is so perfect. He truly captures what it’s like to be a teenager or even just a human being in the modern world. It made me feel nostalgic for seeing the world from that perspective. His writing is atmospheric and real and familiar and invites so much genuine empathy for each character. I would have happily spent more time in this book.
