R.J. MacCready

When a Japanese submarine is discovered abandoned deep in the Brazilian wilderness, a smart, adventurous, and tough zoologist must derail a catastrophic plot in Hell's Gate. 1944. As war rages in Europe and the Pacific, Army Intel makes a shocking discovery: a 300-foot Japanese sub marooned and empty, deep in the Brazilian interior. A team of Army Rangers sent to investigate has already gone missing. Now, the military sends Captain R. J. MacCready, a quick-witted, brilliant scientific jack-of-all-trades to learn why the Japanese are there-and what they're planning. Parachuting deep into the heart of Central Brazil, one of the most remote regions on the planet, Mac is unexpectedly reunited with his hometown friend and fellow scientist Bob Thorne. A botanist presumed dead for years, Thorne lives peacefully with Yanni, an indigenous woman who possesses mysterious and invaluable skills. Their wisdom and expertise are nothing short of lifesaving for Mac as he sets out on a trail into the unknown. Mac makes the arduous trek into an ancient, fog-shrouded valley hidden beneath a 2000-foot plateau, where he learns of a diabolical Axis plot to destroy the United States and its allies. But the enemy isn't the only danger in this treacherous jungle paradise. Silently creeping from the forest, an even darker force is on the prowl, attacking at night and targeting both man and beast. Mac has to uncover the source of this emerging biological crisis and foil the enemy's plans . . . but will he be in time to save humanity from itself?

Though the fighting has stopped and Hitler is vanquished, a dangerous new war between America and the Soviet Union has begun. Invaluable in defeating the Nazis, accidental crypto-zoologist R. J. MacCready and Yanni Thorne, an indigenous Brazilian and expert in animal behavior, are working for the Pentagon once again. Sent to a mysterious Greek island in a remote corner of the Mediterranean, they are investigating rumors about a volcanic spring with "miraculous" healing properties that the locals say is guarded by sea monsters from ancient legends. The islanders believe that, like Fatima, the spring is a gift from God. To the Greek Orthodox Church, it is a sign of a deadly evil foretold in apocalyptic texts. Alongside French and Chinese researchers-men who share their strange, blood-stained past-Mac and Yanni discover that the volcanic spring's undersea plumes release an exotic microbe that can transform life with astonishing speed. To find the source of the Volcanic spring, Mac and Yanni must find a way to neutralize "the Dragons of Revelation"-a fearsome aquatic species also known as "Kraken," which are preventing the scientists from exploring deep beneath the sea's surface. Mutating at an astonishing pace, the Kraken have evolved into a chillingly high alien intelligence. As the race to possess the "miracle" microbe heats up, tensions between geopolitics, religion, and ordinary scientists confronted with the unknown escalate into chaos. Mac and Yanni know all too well that one wrong choice can easily set in motion a biological chain reaction that will reach across the decades to enhance-or destroy-everything that lives.
