I’ve seen some reviews that disliked the quick descent into violence and less than realistic plot, and while I see where they’re coming from… I don’t care. I really really enjoyed this book. I’ve seen a lot of people pitch it as “scratch your Yellowjackets itch” and it absolutely is the right vibes for that. 
Mostly high schoolers and some management are left to tend to an amusement park during a massive hurricane that leaves them stranded in the park with water as far as the eye can see. It keeps raining for a month, so rescue efforts de-prioritize a place corporate leaders say seems under control. Panic strikes when the power goes down in the shelter, and when everyone emerges from shelter, they split into groups, mostly defined by what they did in the park before. The story is told through interviews with the survivors. The only thing I was really missing was some follow up for the second half of interviews with the early people, a couple of the tribes had no one speak in the second half. If you love Yellowjackets or nonfiction like Closed for Storm, I highly recommend!
