This was quite different from the AGGTM-trilogy as this wasn’t a murder mystery. It was just as thrilling though! I found it a bit more predictable, at least I predicted who the traitor was, but still this is an easy 5⭐️. I was completely emerged into the story and I could picture that camper right in front of me. I also read this in like 2 sittings, which is not very common for me. 
I really recommend this book if you’re looking for a thriller that is not very scary, but still very tense and reads very fluently.
