This book was such a page turner! It had me guessing at every step of the way! I consider myself to be a pretty quick study when it comes to figuring out the mystery involved in most books. However, it took me ages to figure this out! I would definitely argue that this is along the lines of Gone Girl and Girl on the Train, in terms of the mystery and the psychological elements. However, this story has a unique spin to it as well. If you're someone who is even remotely interested in either of those genres, I would absolutely recommend this book! Even if you're not someone who generally likes "other woman" stories or psychological thrillers, there are many aspects that still may appeal to you!
