Loved the characters in the book. Ruby, Chubs, Liam, and Zu were the characters for most of the book. They were different from each other, but they weren't complete opposites with nothing in common. My favorite part was probably the relationship the four had with each other. The book did not solely focus on the couple getting together. A lot of it was about the dynamic of the four and the way the world has been reduced to. definitely worth reading
