This book completely wrecked me. It's by far the most bizarre book I've ever read, but also one of the most moving. I started crying by the end.
Yes, the surrealism can be hard to get past, and I would expect that this book isn't for everyone. However, despite the strangeness of the plot and the characters, King is able to make her reader empathize completely with her narrators. Even though you don't fully understand what's happening, you will fully understand the feeling that she's trying to get you to connect with.
This is a book that will sneak up behind you and rip your heart out. It will blow you away. It will turn you inside out.
