For some reason I find this genre particularly fascinating so I thought a thread might be in order to highlight the best of the genre.
My Recommendations:
The Road by Cormac McCarthy
Station Eleven by Emily St John Mandel
The World Without Us by Alan Wiseman - This one isn't a novel but (educated) speculation on what would happen if people just disappeared.
The Passage by Justin Cronin
There is another one that I liked but have totally forgotten the name and cannot find it...
Anyway please share any recommendations you may have even if they're pretty obvious like mine
