Russell Hoban was always somewhat peripatetic in his writing interests. While he tended to return to the same themes, he was far less loyal to genres. “Riddley Walker” is one of his best known novels, and as the only major work of science fiction he wrote, is representatively unrepresentative of his oeuvre.
It concern a young man in a world (ours, about two millennia after a nuclear war) who stumbles on a plan to build a super-weapon. The novel took Hoban more than five and half years to write, and won the John W. Campbell Memorial Award for best science fiction novel in 1982, as well as an Australian Science Fiction Achievement Award in 1983. (It was also nominated for the Nebula Award for Best Novel in 1982, but lost to Gene Wolfe’s “The Claw of the Conciliator”.)
