Welcome to New Crobuzon, a sprawling, squalid industrial megacity where steampunk technology, bizarre magic, and nightmarish alien species collide. When an eccentric, rogue scientist named Isaac is hired to restore flight to a wingless bird-man, his biological experiments accidentally unleash a Slake-moth—a hypnotic, reality-warping predator that feeds on human dreams and sanity. As the creature triggers a psychic plague that threatens to consume the city, Isaac must navigate a corrupt totalitarian government, the criminal underworld, and a renegade artificial intelligence to hunt down the monster. The definitive masterpiece of the "New Weird" genre, this colossal novel is a breathless, gothic, and staggeringly imaginative ride through a dark world you will never forget.
