Lots of 1980s Men’s Adventure books were written with apocalyptic themes while the cold war was in full swing. Some of them can be hard to find nowadays in downloadable format, though, but it’s possible to download some of the rare stuff instead of buying tapes and CDs on ebay cough audiobookbay cough.
Of note (all should be available on the usual legal audiobook sites):
The Survivalist (series), by Jerry and Sharon Ahern
The Outrider (series), by Richard Harding
Deathlands and Outlanders (series), by James Axler
Axler in particular was a pseudonym for many authors writing Men’s Adventure in the same series under the Harlequin imprint, so the quality is all over the place. Lawrence James wrote the first dozen or so books in the Deathlands series and most (if not all) of the Outlanders series, and I prefer the ones he wrote to some of the later stuff in the Deathlands series.
That list there probably encompasses 150-200 books. There were probably thousands more written during the height of pulp apocalyptic lit in the 80s, but they are largely ignored by the modern consumer of post-apoc fiction. I guess much of it doesn’t agree with modern “sensibilities”, which is a shame. Outrider in particular is excellent and hilarious bigger-than-life over-the-top comic book ultraviolent gore-fest, and it’s delicious. Think: Mad Max, the novels.
What to expect in this subgenre:
1980s cultural sensibilities (this is a mixed bag for me)
The USSR as the looming existential threat (meh, that didn’t age well)
Hardcore anti-communism (excellent, not enough of that in mainstream post-apoc lit)
High entertainment value, low “literary” value (excellent)
Sometimes you want a 5-star meal done just so. Sometimes you want a slab of meat on a bun with a side of baked beans. Much of this stuff is the latter. Which is great. But you just don’t want to get on a diet of only it.
(PS: Speaking of The Survivalist, we ought to put the Detonics Combat Master into CDDA, just for homage luls, if it isn’t in there already. Jerry Ahern was a co-owner or major shareholder or something in the Detonics firearms manufacturing company, iirc, so there are some amusing self-product-placement in his books, lol.)
(PPS: You may also enjoy the “Going Home” series, also called the “Survivalist” series but not to be confused with Ahern’s, by “A. American.” It is a newer series, circa 2013, that started as a serial fiction on Survivalistboards. It’s more like near-future post-collapse “prepper fiction” than traditional post-apoc lit, but if you are looking for a more realistic portrayal of collapse and the aftermath, this may be something you’d be into.
If you want a female protagonist and a bit more modern sensibilities, I quite enjoyed all of the Kyla Stone books I’ve read so far. Once again, more post-collapse “prepper fiction” than traditional post-apoc lit.
Also, add “The Drowned World” to the list of classic post-apoc lit. Really excellent story, up there with “Alas, Babylon” imo. Also “Damnation Alley”. Great novella, crappy movie.)
(PPPS: Nobody mentioned “Alas, Babylon” yet? The classic post-apoc book, there. Must read for any post-apoc fan, if for historical context within the genre if nothing else. It’s a great story though, too.)
