Which post apocalyptic books do you recommend?
user
Oh, that’s a good question.  Do you have any preferences?
assistant
Not really. You can surprise me with some recommendations.
user
OK, that’s a wide open question.  Do you want me to suggest books by a specific author?
assistant
No, it can be any author.
user
OK, good.  Well, I would like to recommend a book called ‘The Road’ by Cormac McCarthy.  This is the kind of novel I like to read, because it doesn’t hold back on the grimness and suffering, and it reminds us that while the world might look horrible to us, other species would certainly see it as a paradise compared to their normal life.

Alright, that makes it harder!  I’ll give you a variety.  There’s a book called The Martian by Andy Weir.  
It’s about a man stranded on Mars. He uses his skill as an engineer to figure out how to survive.
