Behemoth by Peter Watts

Book Two of the Rifters Trilogy

A hard-edged near-future thriller that follows a band of modified deep‑sea workers and other misfits as an engineered marine catastrophe spirals into global crisis, forcing them to confront surveillance, military power, and the ethical limits of biological and cognitive modification; the story probes survival, autonomy, and what it means to be human when ecosystems and technologies conspire to upend society.
