The Bug by Ellen Ullman

A tense, introspective novel that follows a programmer's obsessive hunt for a mysterious flaw in critical software, using the slow, meticulous work of debugging as a lens to explore the moral ambiguities, corporate pressures, and personal costs of life in the tech world; as the investigation deepens, the narrative exposes how small errors ripple into human consequences and forces the narrator to confront questions of responsibility, identity, and the limits of control in a system designed by fallible people.
