Our view
“Congo” is a brisk lost-world adventure, at its best when the expedition is deep in the rainforest and in trouble. Crichton loads it with science and technical detail, which gives the hunt for diamonds a convincing surface, though some readers feel it stalls the action. Some also find the characters functional rather than likeable and the book dated; readers after an old-fashioned jungle thriller may not mind either.

About the book
Congo is a 1980 lost world science fiction novel by Michael Crichton, the fifth under his own name and the fifteenth overall. The novel centers on an expedition searching for diamonds and investigating the mysterious deaths of a previous expedition in the dense tropical rainforest of the Congo. Crichton calls Congo a lost world novel in the tradition founded by Henry Rider Haggard's King Solomon's Mines, featuring the mines of that work's title.
