Used. Mass Market Paperback. Michael Crichton takes a classic lost-world expedition, strips it down to its techno-thriller bones, and drops you straight into the humid hazards of the Central African rainforest. This page-turning 1980 adventure follows a high-stakes search for rare diamonds that quickly goes sideways as researchers investigate the gruesome fate of a previous team. It’s an impeccably researched romp that trades Victorian-era tropes for corporate greed, aggressive primates, and cutting-edge gadgetry. If you like your jungle treks laced with lethal peril and smart science, this monkey business is well worth your time.
