This was a Sigma book but not too much was made of the semi-secret organization in this book.   Gray, Tucker, Kane and Kowalski were the leads in this story.

The Congo is the setting and the villain is an enormously wealthy viper that is preying on the people of the Congo.   He disregards environmental safety and humanity.

The Sigma gang along with a Dr. and biologist find themselves facing a viral infection of monumental proportions.   Animals and plants running amuck.

I particularly liked the afterword by Rollins. He points out the dangers of runaway viruses.   He also explains many of the aspects of the book.  I was impressed with his insight.

I recommend the book.
