Riddley Walker is a unique, fascinating book. It takes places a few thousand years after a nuclear Armageddon in England when a young boy comes across a plan to recreate a weapon from the ancient world.
Literary science fiction is simply science fiction that’s better-written, has more realistic characters, and is more ambitious in exploring deep ideas than other books. Instead of just exploding spaceships and smart-mouthed robots, they can contain wrenching emotions that look at what it actually means to be human.
Its polar opposite would be something pulpy like Amish Vampires in Space.
Fortunately, there’s room for both brilliant, tortured writers and Amish Dracula in science fiction.
