Sigma Force

Twenty years ago, a wealthy British financier disappeared near Ubar, the fabled lost city buried beneath the sands of Oman. Now, an expedition of scientists, led by the financier’s daughter, is finally setting off for the legendary metropolis to unlock the desert’s secrets. What they find, however, is more beautiful than they ever dreamed — and far deadlier. Within Ubar is a powerful energy source that could fuel the entire earth above — if it can be harnessed.

Best-selling author James Rollins' action-packed thrillers have been favorably compared to those of Clive Cussler and Dan Brown. During midnight mass, the massive gothic cathedral in Cologne, Germany, is ransacked by armed monks, ancient relics are stolen, and hundreds of people are murdered. The Vatican secretly requests assistance from the U.S. Dept. of Defense Sigma Force. Commander Gray Pierce and his team begin a harrowing race against a heretical gnostic sect seeking to discover the true nature of the missing bones of the magi.

A sinister fire in a Copenhagen bookstore ignites a relentless hunt across four continents. Arson and murder reveal an insidious plot to steal a Bible that once belonged to Charles Darwin, the father of evolutionary theory. And Commander Gray Pierce dives headlong into a mystery that dates back to Nazi Germany…and to horrific experiments performed in a now-abandoned laboratory buried in a hollowed-out mountain in Poland.  

Something is amiss on the open waters of the Indian Ocean. When a group of adventurers investigates a luminescent pool of water, they come in contact with a deadly organism risen from the depths. To combat this threat, Sigma Force races across the globe searching for a cure that may be hidden within humanity’s genetic code. But elements of an ancient conspiracy want the plague to spread, and they have a mole entrenched within Sigma Force.

A ragged man dies in the arms of Commander Gray Pierce, apparently the victim of an assassination. A bloody coin found in the man’s hand appears to be a stolen relic that dates back to the Oracle at Delphi, and the man turns out to have been a scientist on a secret mission. As Pierce investigates, he uncovers a team of scientists bioengineering savant autistic children in the hopes of creating the next Buddha, Jesus, or Muhammad. While they trust this prophet will be a harbinger of peace, things quickly spin horribly out of control.

This sixth book features Commander Gray Pierce in a race against time to solve an ancient riddle—one that prophesies the world's destruction. Pierce will have to journey from the Roman Coliseum to the icy peaks of Norway to uncover the Doomsday Key in time.

Hot on the heels of his New York Times best-sellers Altar of Eden and Doomsday Key, James Rollins' The Devil Colony finds the members of Sigma Force pitted against a dark cabal that has been pulling the strings of U.S. history since its founding. Bodies arranged in a ritual manner are discovered in an Indian cave, and only Sigma Force director Peter Crowe recognizes them for what they are—a warning portending further violence.

Deep in the Rocky Mountains, a gruesome discovery - hundreds of mummified bodies - stirs international attention and fervent controversy. Despite doubts about the bodies’ origins, the local Native American Heritage Commission lays claim to the prehistoric remains, along with the strange artifacts found in the same cavern: gold plates inscribed with an unfathomable script. During a riot at the dig site, an anthropologist dies horribly, burned to ashes in a fiery explosion in plain view of television cameras.

A yacht bearing a young American couple is attacked by Somali pirates, leading to bloodshed and the violent kidnapping of the pregnant woman on board. To aid in her rescue from the lawless and war-torn jungles of coastal Africa, Sigma Force enlists the aid of a unique search team. 

In the wilds of Mongolia, a research satellite has crashed, triggering an explosive search for its valuable cargo: a code-black physics project connected to the study of dark energy — and a shocking image of the eastern seaboard of the United States in utter ruin. At the Vatican, a package arrives containing two strange artifacts: a skull scrawled with ancient Aramaic and a tome bound in human skin. DNA evidence reveals that both came from the same body: the long dead Mongol king Genghis Khan.   

A military research station buried in the remote Sierra Nevada Mountains of Northern California broadcasts a frantic distress call that ends with a chilling order: "This is sierra, victor, whiskey. There's been a breach. Failsafe initiated. No matter the outcome: Kill us.... Kill us all."
