Book recommendations similar to YJ?

So, confession time. I honestly got into this show (and became super fanatic) all because I was trying to find other shows/book series like the Hunger Games online. You can probably see the connections - group of teens in a survival scenario, exciting narrative, dark atmosphere. I’ve seen some threads about recommendations of other shows to watch in the off-season, but haven’t seen one about books! Does anyone have any recommendations of survival-based stories with thriller elements like YJ or Hunger Games?

And yes, before it’s inevitably recommended, I’ve already started the Red Rising series (which I have to shoutout myself because it’s amazing)
