So , first of all I would like to tell everyone that this book is nothing like The gone girl.Please stop comparing both of them.Every thriller I read I cant understand in the beginning but this one straight from the start took me into it, I formed opinions in my mind and I finished reading it in 1 and a half day.It was that good.JUST ONE thing is faulty that the ending is pretty much quickly done.I mean that one or more chapter could have been given to explain what Rachel does after all this happens, will she ever get married.That, s only why I give this book a 4 star.And seriously I couldnt have predicted that it was Tom all along, I mean he was shown as a good character who cheated on his wife and later revealed that he also cheated on his 2nd wife.It was amusing.THIS book also reveals the negativity we get if we take drugs or drinks.They bring only depression and unhealthy physique.
