When archaeologist Annja Creed is hired to find the lost city of Promise in Brazil, she is more than intrigued. Legends abound of a magical place where slaves were rumored to have discovered the secret to eternal youth and life.

But strangers are not welcome in Promise.

Annja soon learns that the residents have gone to extreme lengths to guard their precious secret. Making her way from the steamy port of Belem to the brutal slums of Northeast Brazil, Annja faces unexpected peril, from poisoned arrows to Amazonian anacondas. As she navigates through a land where spirituality collides with the material world, Annja must distinguish between what is real and what is imagined for fear of making a wrong move. Because anyone or anything could be her enemy.

And she's getting too close...

A priceless artifact could restore a family's honor--or destroy everything in its wake.

While vacationing in Tokyo, archaeologist Annja Creed is approached by a man who desperately needs her help. Kennichi Ogawa, the last descendant of an ancient warrior family, is trying to locate a stolen artifact. Legend has it that the vajra was mystically endowed by a warrior's spirit to help the Yumegakure-ryu family forever be a source for good. But the vajra could help the forces of evil if it gets into the wrong hands. And now the bloodthirsty Yakuza and a group of hired ninja are after it. As Annja and Kennichi trek through the fog-enshrouded mountains of the Iga province to find the relic, they must also outsmart the vicious Yakuza and ninja who are dangerously close to uncovering the vajra first...and to destroying their competition.

Some say they are a cursed people. But those who try to find them will be just as unlucky... Working on a dig on the southern coast of India, the last thing Annja Creed expects is to be hit by a tsunami. Or to strike archaeological gold. But that's exactly what happens when several objects wash ashore in the storm.

The relics carry unfamiliar markings that hint at a legendary city. Excited by the prospect of discovering a culture believed lost to civilization, Annja embarks on a perilous journey deep into the heart of danger.

She learns of a mysterious artifact that could provide clues to the whereabouts of the lost city, which means trekking through an inhospitable jungle and forbidding terrain. But nature's denizens and death traps are not the only threats: someone else is also pursuing the prize. Just as Annja's grail comes into view, she must ward off an even greater evil. Because deep in the Nilgiris mountains is a race of people that the world forgot.

And they don't like strangers.

Finding the relic is a divine quest. Even if it means committing murder.

When a mysterious man orchestrates an attack on archaeologist Annja Creed and then offers her an assignment, Annja is baffled. But the mission is too intriguing for her to refuse. She must find an object that possesses a sacred and powerful secret offering atonement to anyone who uncovers it--or wreaking havoc on the world.

Stolen from an ancient order of knights, the relic is now in the clutches of a band of pirates sailing the South China Sea. When a government leader threatens to destroy the pirate ship--along with the artifact--rather than let it get into the wrong hands, Annja must decide at what cost the sacred prize should be protected. Destroying it would defile history. But saving it could bring about apocalypse.

Their ultimate fear came true. And then things got worse.

Annja Creed jumps at the chance to join a fellow archaeologist on a quest to find a relic. But she's not so thrilled about northern Siberia, where they are hoping to discover something buried in the long-undisturbed soil of Russia's frozen terrain. When they reach the town of Jakutsk, Annja is put off by its gray landscape and highly superstitious inhabitants. They claim they are being hunted. Then one of the villagers goes missing.

The locals blame the Khosadam, a ghost of a fallen goddess said to ingest the souls of the departed. But there are no fresh graves. She is now hunting the living. When Annja seeks to destroy the apparition, she discovers an even more horrifying truth--and may have hit a dead end.

The stranger could be insane. Or he just might be our salvation.

Archaeologist Annja Creed is more than curious when a decrepit, ancient-looking man visits her, claiming the end of the world is near. The stranger spins wild tales and speaks as if he actually knew King Arthur. But, strangest of all, he insists that Annja is the only one who can stop the horrible event that is about to happen.

When Annja's mentor and friend Roux goes missing, she quickly realizes there may be something to the stranger's stories. Making her way through the dark and violent underbelly of Istanbul, Annja must find her missing friend and the Holy Grail before the relic gets into the wrong hands. She may not fully believe the fate of the world is on the line, but she doesn't really want to die finding out.
