I highly recommend this on audiobook. I normally don’t like audiobooks but I can guarantee that had I read this physically I wouldn’t have given it as high of a rating. I felt extremely attached to the characters and felt the dread of each and every one of their situations. I had expected more of a “who’s the murderer” or “there’s someone hiding  on the island” but it was straight forward and simple which I surprisingly liked. By the end I was still half expecting some kind of crazy plot twist but (although there was a plot twist) I appreciated that things were what they were.
