"Bestseller Rollins's epic 12th Sigma Force adventure features exotic locales, heroic quests, quixotic villains, action galore, and enough science and scientific curiosities to titillate even casual readers...Rollins's characters are as large as his landscape in this vast and vastly entertaining thriller saga." -- Publishers Weekly (starred review)

"When it comes to the blending of action, adventure, history, and science, there is no other author who does it better than Rollins. Fans of Clive Cussler, Steve Berry, and Michael Crichton should already have Rollins on their mandatory reading list." -- Booklist (starred review)
