The Beginning of Everything question

I think that this book is one of the most amazing books I've ever read. It's well-written, relate-able in some parts, the plot flows very well, the characters are unique and each has a story that is important to the plot. The thing I love the most about this book is the fact that there is no happy ending where the guy gets the girl of his dreams and they go to college together, because that never actually happens. It makes the book seem that much more realistic and relate-able when Ezra decides to do what he wants to do with his life, and he takes the lessons he learned during his senior year to heart. He even manages to keep most of his geeky friends from high school, which is something I think that most of us aspire to do. There is also one specific paragraph towards the end of the book that really catches the eye and sums up the entire plot of Cassidy's story, "To Cassidy, the panapticon wasn't a metaphor. It was the greatest failing of everything she was, a prison she had built for herself out of an inability to appear as anything less than perfect. And so she ghosted on, in relentless pursuit of escape, not from society, but from herself. She would always be confined by what everyone expected of her, because she was too afraid and too unwilling to correct our imperfect imaginings." I think that this is just the most perfect ending to a most perfect book about a not so perfect boy. It really touches the heart and makes the reader ask questions that they had never thought of before. I recommend this book to anybody who will listen.
