I'm not entirely sure if it's what you're looking for, by I just finished reading The Passage by Justin Cronin. A good chunk of the book is kind of in our society and mostly everyting is right but then something happen and humanity is pretty dead except a couple survivor. I'm guessing that could be qualified as an apocalypse kind of thing because of viral infection?
Anyway, it's pretty good. You might want to check it out in a library before buying it, just in case. Or something.
