Sure. 'The Road' by Cormac McCarthy is a great one. It shows a father and son's journey through a desolate world. Another is 'Station Eleven' which explores the lives of a group of actors and musicians traveling through a post - apocalyptic North America. And 'Mad Max: Fury Road' (which is also based on a post - apocalyptic concept) has a great movie adaptation, and there are related books that are also worth checking out.
I'd recommend 'A Canticle for Leibowitz'. It's set in a post - nuclear - war world and follows the story of a religious order trying to preserve knowledge. 'Oryx and Crake' by Margaret Atwood is also excellent. It presents a world devastated by genetic engineering gone wrong. There are complex characters and a really interesting take on what could happen in a post - apocalyptic scenario.
One more is 'The Hunger Games' series. While it's more of a dystopian/post - apocalyptic blend, it has elements of survival in a harsh world. The main character, Katniss, has to fight for her life in a deadly arena. And 'The Stand' by Stephen King is a classic in the post - apocalyptic genre. It has a large cast of characters dealing with a world after a super - flu has wiped out most of the population.
