When I finished Death Of Grass, I was amazed to find it was written in the 1950s. It feels very modern, and must have been shocking stuff at the time.
It was. As I said, the British SF market was all cosy catastrophe (it's when the expression dates from). These tended to gloss over the breakdown in civilisation and cut straight to the middle-class agrarian utopia without all those peasants who were now safely dead. See "Earth Abides" for the US version (I think it's now a TV series?).
John Christopher's "The World in Winter" is good as well - one year winter simply doesn't end and a new Ice Age has slowly begun. But that means no crops can be grown in places like the US and Europe. They start looking at the now temperate areas in the old tropics with a covetous eye.
Currently I'm reading "In Accension" by Martin MacInnes. He's a mainstream literary writer who dabbles around the edges of genre writing. It means that the critics like him, but his book comes across as tremendously well-written not very good SF. Not much happens, but it doesn't happen in great style. It's a good book, but it's clearly aimed at literary readers, not SF readers.
Before that was Mo Hayder's "Birdman", a hunt-the-serial-killer book. Well written, just not a genre that interests me. The twist was well done, but I'm not going to bother with others in the series. I will try at least one of the standalones though. And I still recommend her book "The Book of Sand".
I also went back to re-read Brian Stableford, after the author's death earlier this year. I have a few of his books from many years ago, so I tried the first Grainger book, but didn't like enough this time around to bother with the other five. I did enjoy "Empire of Fear" again though. An SF vampire book, high on biology and low on horror. It is set in an alternate world, starting in 1606, where the leading rulers of Europe are a cadre of vampires, let by Vlad Tepes and Richard the Lionheart. Meanwhile, a group of proto-scientists try to work out how vampires are created...
