Gone Girl by Gillian Flynn

I waited quite a while for this book. I read the review in the New York Times (http://www.nytimes.com/2012/05/30/books/gone-girl-by-gillian-flynn.html) and was really excited to read it. And I was not disappointed. It was a psychological thriller that has twists and turns in each and every chapter. And some of them are short!
Her writing is really amazing. Ms. Flynn is a gifted writer.  On the one hand, I wanted to race through the book to follow the intrigue and drama; on the other hand, I wanted to savor her writing and her deep probing into the minds of these characters. The book is written in the first person from the point of view of the two protagonists: Amy and Nick. They are a married couple who are "celebrating" their fifth anniversary at the opening of the book. But that same day, Amy disappears. I don't want to give anything away, but will say that both of the characters have dark sides that are revealed slowly over time, so that the characters that you meet in the first 50 pages are very different people than those described on the following pages.
I raced through this book in just a couple days, which I am sure is the case with many of the readers.
What will hold me like this book next? It's a tough act to follow!
