This started off so well, and I was eager to see how the story unfolded after the contestants settled in and then the crew suddenly disappeared. However, the book grew pretty dark and not much really happened. I kept reading because I wanted to know what happened, and I'm sorry I was so disappointed given how good the first half is. However, the ending is abrupt and pretty vague. It turns out the answers are probably buried in the middle, and I wish they would have been confirmed in the end. I won't be recommending this.
