Edwards must have written this book with the intention of keeping you up all night, not only because you can't wait to see what happens next but it has some seriously disturbing scenes. The average read time on this one for all members of our group was less than one week. If that doesn't tell you how fast paced, gotta know what happens next kinda read it was I don't know what will. Definitely fits that thrill, big twist at the end, didn't see that coming type of read. If I were to compare it to something popular now I would say Gone Girl or Girl on the Train, this is just better!
