A review by eeclayton
Congo, by Michael Crichton

3.0

An expedition looking for blue diamonds in Congo are brutally attacked. A second expedition is sent to find out what happened and find the diamonds. This second group includes a gorilla who communicates via sign language. While they're racing against their competitors, they have to face not only the harsh African jungle environment, but also the mysterious beasts that killed the first group.
You'll need a healthy amount of suspension of disbelief for this book, and also patience with all the tech talk about gadgets and innovations that I'm sure were groundbreaking in 1980 but might not be that impressive in 2020.
Nevertheless, it's a fast-paced story with something always happening, and I found it really entertaining.
