This honestly may be my favorite of Reid's books so far. She took a character who, on the surface, seems like she's going to be very unlikeable and emotionless, and gives her more depth than you expect, and makes you truly care about her. This book was fantastic. It felt like I was watching her tennis matches - suspenseful, full of ups and downs and I didn't want to put the book down. It was exultant and heartbreaking, and I really think it's her best novel yet.
