In my opinion, this is one of Gillian Flynn's best works (my #2 being "Dark Places" followed by "Sharp Objects")! I hope she is in the process of writing more books - I will heavily anticipate upcoming stories. In true Gillian Flynn fashion, there were several unexpected twists in the book (e.g. Diary Amy, the Desi plotline, PART 3) that kept me hooked page after page. As soon as I finished, my partner and I burst into "what the heck" mode and discussed every storyline in the book. I'm excited to watch the film adaptation to see how it holds true to the book!
