James Rollins - Sigma Force (#1-10 inc 6.5 &7.5)

Sandstorm (#1)
A freak explosion in the British museum in London ignites a perilous race for an earth-shaking power source buried deep beneath the sands of history. Painter Crowe is an agent for Sigma Force, a covert arm of the Defense Department tasked with keeping dangerous scientific discoveries out of enemy hands. When an ancient artefact points the way toward the legendary "Atlantis of the Sands," Painter must travel across the world in search of the lost city-and a destructive power beyond imagining.

But Painter has competition. A band of ruthless mercenaries, led by a former friend and ally, are also intent on claiming the prize, and they will destroy anyone who gets in their way.

Ancient history collides with cutting-edge science-with the safety of the world at stake!

Map of Bones (#2)
During a crowded service at a cathedral in Germany, armed intruders in monks' robes unleash a nightmare of blood and destruction. But the killers have not come for gold; they seek a more valuable prize: the bones of the Magi who once paid homage to a newborn saviour . . . a treasure that could reshape the world.

With the Vatican in turmoil, Sigma Force under the command of Grayson Pierce leaps into action, pursuing a deadly mystery that weaves through sites of the Seven Wonders of the World and ends at the doorstep of an ancient, mystical, and terrifying secret order. For there are those with dark plans for the stolen sacred remains that will alter the future of humankind . . . when science and religion unite to unleash a horror not seen since the beginning of time.

Black Order (#3)
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. 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 in Poland.

A continent away, madness ravages a remote monastery in Nepal, as Buddhist monks turn to cannibalism and torture. Lisa Cummings, an American doctor investigating the atrocity, is suddenly a target of a brutal assassin. And Lisa's only ally is Painter Crowe, director of SIGMA Force, who already shows signs of the baffling malady.

Now it is up to Gray Pierce to save them both as SIGMA Force races to expose a century-old plot that threatens to destroy the current world order . . . and alter the destiny of humankind forever.

The Judas Strain (#4)
From the depths of the Indian Ocean, a horrific plague has arisen to devastate humankind--a disease that's unknown, unstoppable . . . and deadly. But it is merely a harbinger of the doom that is to follow. Aboard a cruise liner transformed into a makeshift hospital, Dr. Lisa Cummings and Monk Kokkalis--operatives of SIGMA Force--search for answers to the bizarre affliction. But there are others with far less altruistic intentions. In a savage and sudden coup, terrorists hijack the vessel, turning a mercy ship into a floating bio-weapons lab.

A world away, SIGMA's Commander Gray Pierce thwarts the murderous schemes of a beautiful would-be killer who holds the first clue to the discovery of a possible cure. Pierce joins forces with the woman who wanted him dead, and together they embark upon an astonishing quest following the trail of the most fabled explorer in history: Marco Polo. But time is an enemy as a worldwide pandemic grows rapidly out of control. As a relentless madman dogs their every step, Gray and his unlikely ally are being pulled into an astonishing mystery buried deep in antiquity and in humanity's genetic code. And as the seconds tick closer to doomsday, Gray Pierce will realize he can truly trust no one, for any one of them could be . . . a Judas.

The Last Oracle (#5)
In Washington, D.C., a homeless man takes an assassin's bullet and dies in Commander Gray Pierce's arms. A bloody coin clutched in the dead man's hand--an ancient relic that can be traced back to the Greek Oracle of Delphi--is the key to a conspiracy that dates back to the Cold War and threatens the very foundation of humanity. For what if it were possible to bioengineer the next great prophet--a new Buddha, Muhammad, or even Jesus? Would this Second Coming be a boon . . . or would it initiate a chain reaction that would result in the extinction of humankind?

Vital seconds are ticking rapidly away as Pierce races across the globe in search of answers, one step ahead of ruthless killers determined to reclaim the priceless artefact. Suddenly the future of all things is balanced on the brink between heaven and hell--and salvation or destruction rests in the hands of remarkable children.

The Doomsday Key (#6)
At Princeton University, a famed geneticist dies inside a biohazard lab. In Rome, a Vatican archaeologist is found dead in St. Peter's Basilica. In Africa, a U.S. senator's son is slain outside a Red Cross camp. The three murders on three continents bear a horrifying connection: all the victims are marked by a Druidic pagan cross burned into their flesh.

The bizarre murders thrust Commander Gray Pierce and Sigma Force into a race against time to solve a riddle going back centuries, to a ghastly crime against humanity hidden within a cryptic medieval codex. The first clue is discovered inside a mummified corpse buried in an English peat bog—a gruesome secret that threatens America and the world.

Aided by two women from his past—one his ex-lover, the other his new partner—Gray must piece together the horrifying truth. But the revelations come at a high cost, and to save the future, Gray will have to sacrifice one of the women at his side. That alone might not be enough, as the true path to salvation is revealed in a dark prophecy of doom.

Sigma Force confronts humankind's greatest threat in an adventure that races from the Roman Coliseum to the icy peaks of Norway, from the ruins of medieval abbeys to the lost tombs of Celtic kings. The ultimate nightmare is locked within a talisman buried by a dead saint—an ancient artefact known as the Doomsday Key.

The Skeleton Key (#6.5)
Seichan is ripped out of the Sigma series for an adventure all her own—but can she survive? The beautiful and elusive assassin wakes in a hotel in Paris with a deadly electronic collar fastened to her throat. Joined by a boy who is similarly threatened, she must rescue the son of a hated enemy, who has fallen under the sway of the nefarious leader of an apocalyptic cult. To survive, she must venture into the dark world beneath the City of Lights, into the infamous catacombs of Paris. Caught between two enemies, she must fight for her life…while time ticks down toward a fiery apocalypse. But in the dark, surrounded by the mouldering bones of the dead, even success does not equal survival. In the end, the only true hope for the world lies in a stunning act of betrayal.

The Devil Colony (#7)
Could the founding of the United States be based on a fundamental lie? The shocking truth lies hidden within the ruins of an impossibility, a lost colony of the Americas vanished in time and cursed into oblivion. A place known only as The Devil Colony.

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. All evidence points to a radical group of Native Americans, including one agitator, a teenage firebrand who escapes with a vital clue to the murder and calls on the one person who might help--her uncle, Painter Crowe, Director of Sigma Force.

To protect his niece and uncover the truth, Painter will ignite a war among the nation's most powerful intelligence agencies. Yet an even greater threat looms as events in the Rocky Mountains have set in motion a frightening chain reaction, a geological meltdown that threatens the entire western half of the U.S.

From the volcanic peaks of Iceland to the blistering deserts of the American Southwest, from the gold vaults of Fort Knox to the bubbling geysers of Yellowstone, Painter Crowe joins forces with Commander Gray Pierce to penetrate the shadowy heart of a dark cabal, one that has been manipulating American history since the founding of the thirteen colonies.

But can Painter discover the truth--one that could topple governments--before it destroys all he holds dear?

Tracker (#7.5)
Off the streets in the medieval heart of Budapest, Captain Tucker Wayne and his war dog, Kane, rescue a mysterious woman fleeing three armed men. The secret she holds will unlock a terrible treasure, one steeped in blood and treachery, tied to a crime going back to the fall of Nazi Germany and a heritage of suffering and pain that reaches out from the past to wreak havoc today. In a final showdown in the depths of a lost cemetery, truths will be unearthed, treasures exposed, and the fate of all will rest upon the shoulders of one man and a dog whose courage is beyond measure.

Included with this thrilling story is sneak peek at Bloodline, where the further exploits of Tucker and Kane will be revealed.

Bloodline (#8)
Galilee, 1025. Infiltrating an ancient citadel, a Templar knight uncovers a holy treasure long hidden within the fortress's labyrinth: the Bachal Isu -- the staff of Jesus Christ -- a priceless icon that holds a mysterious and terrifying power that promises to change humankind forever.

A millennium later, Somali pirates hijack a yacht off the coast of the Horn of Africa, kidnapping a young pregnant American woman. Commander Gray Pierce is enlisted for a covert rescue mission into the African jungle. The woman is no rich tourist: she's Amanda Gant-Bennett, daughter of the U.S. president.

Suspicious that the kidnapping masks a far more nefarious plot, Gray must confront a shadowy cabal which has been manipulating events throughout history...and now challenges the current presidency.

For this unique mission, SIGMA is aided by a pair of special operatives with unique talents: former Army Ranger Captain Tucker Wayne and his military war dog, Kane. But what should be a straightforward rescue turns into a fiery ambush and a deadly act of betrayal, as Gray and his team discover that the hostage is a pawn in a shattering act of terrorism with dark repercussions. And the danger is only beginning...

Halfway around the world, a firebombing at a fertility clinic in South Carolina exposes a conspiracy that goes back centuries...a scheme that lies within our genetic code. With time against them, SIGMA must race to save an innocent unborn baby whose very existence raises questions about the nature of humanity, asking:

Could you live forever?

Would you live forever?

The Eye of God (#9)
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 artefacts: 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.

Commander Gray Pierce and Sigma Force set out to discover a truth tied to the fall of the Roman Empire, to a mystery going back to the birth of Christianity, and to a weapon hidden for centuries that holds the fate of humanity.

The 6th Extinction (#10)
A remote military research station sends out a frantic distress call, ending with a chilling final command: Kill us all! Personnel from the neighbouring base rush in to discover everyone already dead-and not just the scientists, but every living thing for fifty square miles is annihilated: every animal, plant, and insect, even bacteria.

The land is entirely sterile-and the blight is spreading.

To halt the inevitable, Commander Gray Pierce and Sigma must unravel a threat that rises out of the distant past, to a time when Antarctica was green and all life on Earth balanced upon the blade of a knife. Following clues from an ancient map rescued from the lost Library of Alexandria, Sigma will discover the truth about an ancient continent, about a new form of death buried under miles of ice.

From millennia-old secrets out of the frozen past to mysteries buried deep in the darkest jungles of today, Sigma will face its greatest challenge to date: stopping the coming extinction of mankind.

But is it already too late?
