This book was MESSED UP on so many levels. That was basically all I could thing about throughout the entire book. Having read Gillian Flynn's other books, I knew not to attempt to guess what happens, who the killer(s) are. So while I was NOT guessing what was going on I couldn't stop thinking about how truly messed up the story was. It is a great book to sink your teeth into, but don't expect to stop once you get going.
