Edge of your seat action and mystery keeps one invested in turning page after page into the wee hours of the night. Well done and full of intrigue and scientific facts that are chilling in real life.

This is the 11th book in the Sigma Force series. It starts out in the mountains of Croatia. A research lab is conducting a study of the evolution of human intelligence that involves a primate gorilla named Baako. The book continues to give us a premise of going to Atlantis which is a totally new concept that I didn't fully believe in. I did enjoy this book but had to rate it a 4.0 because of Atlantis being shown as part of the concept. If you like books about gorilla research then you will love to read this book. Recommended!
