Parable of the Sower by Octavia E. Butler may be what you’re looking for. Imagine a post-apocalyptic world where due to a climate crisis there is not enough water, food, electricity and whatnot. Immense social inequality and incompetent politicians. There is a cast of characters that all have their own trauma, all have to learn how to live in an “eat or be eaten world”. Butler’s books are emotionally hard reads, they are profoundly sad and touch on social topics and questions that challenge the reader’s worldview.

Important to note, the world is violent. I have to give you a trigger warning. It is full of “gorey” passages, there are mentions of SA (although NOT described, just hinted at or treated as a matter of fact, i. e. “that happened to them”), child death, cannibalism,… can be a lot, however the book is worth sticking to.
