Even though I knew Gillian Flynn was an amazing writer, I was still blown away by this book. She is so brilliant and encaptures the minds of characters so well, as well as having a variety of different types of characters. I was so enveloped in this book, I was literally terrified at some points and couldn't sleep until I finished the whole book and watched some funny YouTube videos after. If you're looking for a good mystery/thriller, THIS is the book to read.
