This is a spoiler-free review.

Let me start by saying that this book's synopsis is absolutely misleading. The 'action' part of the book is just the last 50–70 pages. The rest of it is young adults partying on an isolated island, despite claiming to be a forced proximity thriller. It is proximity, alright, but where is the suspense? 

My biggest problem with this book right from the start is how much of a pushover the FMC is. Her boyfriend is indifferent towards her, and that is established in a hundred different ways, but she keeps going back for more. I just don't get it. As I was reading this book, I constantly paused and kept notes on how unbelievably, ridiculously stupid she was, and that says A LOT. I couldn't care less about the rest of the characters, since they were all stupid and didn't really have any motives for their actions. 

The plot was full to the brim with plot holes and unanswered questions, leading to a preposterous ending. I can excuse all of these things if I'm having fun with a book, but this was certainly not the case with this one.
