After Make Room! Make Room!
The Sheep Look Up by John Brunner
If you loved how Make Room! Make Room! refused to sugarcoat overpopulation's grind, The Sheep Look Up takes that unflinching realism and cranks it to suffocating intensity—air as poison, water as weapon, society choking on its own consumption. Same brutal honesty about systemic rot, same refusal to rescue you with heroes or flashy tech, just a mosaic of fragmented lives collapsing under ecological disaster that reads like tomorrow's autopsy report.
