The Godwhale by T.J. Bass

In a grim post-human future where people have been reorganized into efficient hive communities and much of individuality has been bred or engineered away, an awakened protagonist becomes entangled with a colossal bioengineered sea creature that functions as a living recycling vessel and repository of lost memories. Together they confront the ecological and moral fallout of technocratic “perfection,” struggle to preserve fragments of human language, identity and genetic legacy, and force a reckoning with the costs of extreme population control, medical manipulation, and social homogenization.
