Reading List: Gone Girl

I had never heard of this book until my friend read it and started raving about it. I trust her when she says a book is a "must read" so of course I had to pick it up. After reading the first couple chapters, it's kind of slow getting into but she assured me that it does pick up and get more interesting. Apparently it's going to be made into a movie so I must get it read before October, which shouldn't be a problem since I do my best reading on a plane and I will be traveling back to Maryland next week via plane. 

Has anyone read this yet?!
