Congo (1980) by Michael Crichton is a techno-thriller that blends adventure, science, and corporate intrigue in the heart of Africa. The story follows an expedition to the Congo rainforest, where a team—including primatologist Karen Ross, mercenary hunter Charles Munro, and Amy, a gorilla trained in sign language—seeks to recover rare blue diamonds and investigate the mysterious disappearance of a previous team. Their journey leads them to the lost city of Zinj, where they encounter hostile tribes and a race of aggressive, territorial gray gorillas.
Crichton’s signature mix of cutting-edge science (satellite tech, primate communication) and relentless pacing keeps the tension high, though some elements (like Amy’s sign-language quips) verge on camp.
A gripping, if dated, precursor to Jurassic Park’s bio-thriller themes.
