3.5 rounded up to 4 due to the twist at the end and the entertainment of this book. I would have to say some of the plot is very familiar to a well known horror move but I will not say as it will spoil the plot. I would say that there does need to be more descriptions of the characters, I still really have no idea what anyone looked like and did not know the main character’s name until a couple chapters in. You have to go into this book knowing it’s a YA thriller and a quick, fun, read.
