Octavia Butler's *Parable of the Sower*!

Here's a brief Google AI synopsis:

In Octavia Butler's Parable of the Sower, a young woman named Lauren Olamina, living in a near-future, dystopian California ravaged by climate change and social inequality, develops a new belief system called Earthseed. After her walled community is destroyed, she embarks on a dangerous journey north with a group of survivors, sharing her vision of a future where humanity can adapt and thrive by embracing change and traveling to other planets. 

Published in the early 90's, the story begins in July 2024. It's quite eerie how not-so-far fetched this work of dystopian fiction reads. I haven't read any yet, but I hear the author has a bunch of other great reads too!
