User mhj put out a request for "recommendations for post-
apocalyptic fiction."[1] While I'm not an expert on the
genre, I do enjoy it; though, I conflate "post apocalyptic"
with "dystopian" usually, even though they aren't always the
same thing. I'd like to humbly suggest three dystopian
novels to read toghether:

   First:  "We" by Yevgeny Zamyatin, considered I believe to
           be the granddaddy of dystopian novels.[2]

   Second: "Anthem" by Ayn Rand, a short dystopian "novella"
           that is also a libertarian utopian-vision promo.
           Also in the granddaddy category.[3]

   Third:  "The Iron Heel" by Jack London, from his heavier
           pro-socialism days. Also a granddaddy.[4]

The three novels, I feel, give a fascinating view of what
actually thrust the world into the dystopian condition. It's
fascinating to see what different authors feel would cause
the downfall of humanity.

And for a more modern experience, "The Dog Stars" by Peter
Heller. It's about a pilot living in a post apacolyptic
world with his dog and a military fellow. It's a little
over-done with needless swearing, I felt, and there's a
sex scene in there that was out-of-place, but the overall
feel of the book was interesting. Mostly this one was
trying too hard, but it's lighter on the philosophy and
idealism, if you prefer that.
