Centuries later, a battered journal—the only evidence left from the night of the Romanovs' execution—turns up in a rare bookstore. As the U.S. and Russians vie for the truth, and the lost Romanov treasure, they collide with a prehistoric predator thought long-extinct.
It's up to the Event Group to lay to rest the legends. On an expedition into the wilds of British Columbia, Colonel Jack Collins and his team make a horrifying discovery in the continent's last deep wilderness, where men have been vanishing for centuries.
Meanwhile, Iran is preparing for the return of the prophet. Israel is threatening nuclear war. And the details about Alex's special U.S. military venture—code name: Arcadian—have been stolen. Then another gamma spike is detected...and someone, or something, is draining the fluids from the bodies of Iranian soldiers in the desert.
Now it's up to Alex to follow the traces of radiation all the way to the ancient caves of Arak, where he'll come face to face with a creature from his darkest nightmares. Is it game-over for Alex and his team? Or are greater forces at work as the world reaches its natural end—and mankind casts its final judgment?
The year 1533: Sent by Francisco Pizarro, Captain Hernando Padilla and his small Spanish expedition found the legend that men had only dared to whisper. In a lost valley deep in Brazil, he discovered what had driven men of greatness into sheer madness: El Dorado, the largest gold deposit in the world, hidden away from the march of time, preserved as the pristine Eden of wondrous sights and forgotten people.
But what he found wasn't just gold.
Instead, Padilla and his crew awakened a devil hidden in the lost valley, a beast of the Amazon who rises from the mother of all waters to viciously kill any who threaten the secret of the long-vanished Incas. But one soldier survives the bloody savagery and, before dying, shares his story with a lone priest in Peru. A secret the Vatican quickly buried away.
The Present: Professor Helen Zachary is searching for a hidden legend, buried deep within the Amazon Basin---a great beast who has survived there since the dawn of time, a being ready to plunge modern science into a world of darkness. And into this darkness, Professor Zachary and her team vanish.
Now a letter from a colleague of Zachary's sends the Event Group, led by Major Jack Collins, chasing down the professor's lost expedition and into the legendary darkness of the Amazon. Dedicated to discovering the truth behind the myths and legends propagated throughout world history, the Event Group---an agency within the U.S. government that officially doesn't exist---ensures that mistakes from the past are never repeated. They are a dedicated collection of the nation's most brilliant men and women of science, philosophy and the military.
Using cutting-edge technology exclusively designed for the Event Group by the U.S. military, they travel from Brazil to the Little Bighorn, from Columbia to the hallowed grounds of Arlington National Cemetery. As they do, the Event Group faces mounting opposition from several different adversaries bent on either discovering the whereabouts of El Dorado . . . or trying to bury the legend forever.
