Deep in the Caribbean Sea, a nuclear submarine is forced to suddenly abort its mission under mysterious circumstances. Strange facts begin to emerge that lead naval investigator, John Clay, to a small group of marine biologists who are quietly on the verge of making history.

With the help of a powerful computer system, Alison Shaw and her team are preparing to translate the first two-way conversation with the planet's second smartest species. But the team discovers much more from their dolphins than they ever expected when a secret object is revealed on the ocean floor. One that was never supposed to be found.

Alison was sure she would never trust the military again. However, when an unknown group immediately becomes interested in her work, Alison realizes John Clay may be the only person she can trust. Together they must piece together a dangerous puzzle, and the most frightening piece, is the trembling in Antarctica.

To make matters worse, someone from the inside is trying to stop them. Now time is running out...and our understanding of the world is about to change forever.

Facing the cold, clear glass, Alison Shaw stared nervously into the giant seawater tank.

It was just one year ago that she and her team of marine biologists had stunned the world with their incredible breakthrough. And now, they were about to do it again.

But an ocean away, something strange was unfolding. Along a lonely coast in South America, an experimental Russian submarine, long thought to have been dismantled, has suddenly resurfaced. And the U.S. Navy has taken notice, sending officers John Clay and Steve Caesare to investigate.

The sub has been studying a group of unmarked soldiers. Disappearing into the jungle each night beneath the cover of darkness. Something has been discovered...something big.

And it's about to fall into the wrong hands. Unless Alison Shaw and her team can find something that no one else can.

In 1984 a doomsday vault was constructed on a remote island in the Arctic Ocean.

Its purpose was to preserve Earth’s genetic history in the event of a global catastrophe.

Now, decades later, a second vault has been uncovered.

This one resting where no one ever expected.

And the problem is…it’s not ours.

Yet even more curious than the vault itself, is what lies inside.

Seeds. Millions of seeds. Each with a genetic embryo untouched and perfectly preserved.


No one knows who built it. Or when.

What we have managed to figure out is that whoever it was traveled an immense distance. For the sole purpose of hiding their genetic blueprints on Earth.

But why?

Now a small group of marine biologists and navy investigators have been assigned to find out. Before anyone else does.

But Alison Shaw and John Clay are not prepared for what they are about to uncover.

Beginning with the truth behind our own evolution.

It began in Ethiopia, hundreds of thousands of years ago. When a handful of genetic mutations caused evolution to split from the primates. And mankind was born.

Now, eons later, evidence of more splits from the apes are being unearthed. And with them, a disturbing realization. Ours was only one of many.

And yet we survived. But it was not by luck or chance. We survived because humans had something the others did not. A unique ingredient that has only now been rediscovered.

First in the mountains of South America, where it was promptly destroyed by the Chinese. And now a second source in Africa. The epicenter of mankind's very inception.

A place that John Clay and Alison Shaw must find quickly. Because the Russians already know what we are searching for. And the Chinese want back what is rightfully theirs.

The mother of all secrets awaits the world, in Africa. One that will not only explain who we are, but will decipher the very code within our own DNA.

The world is losing hope.

Political and social infighting threaten to destroy the world. Rancor and hatred only grow stronger, engulfing entire nations. And each day moral and economic strife brings embroiled countries ever closer to war.

But hope is not dead. Everywhere, pockets of honor and compassion continue to persevere. Where human lives are cherished and valor endures. And one small, extraordinary group fights to save us all.

A team in possession of the mother of all secrets. The one secret – the one discovery – that could bring the world back from the brink.

It began with a breakthrough. In interspecies communication. Leading both John Clay and Alison Shaw through a series of startling discoveries and life-altering revelations. Divulging who we really are as a species. Why we are here...and who is here with us.

And the greatest lesson of all, that our brains are not as rare and unique as humans had assumed. But rather just one of three brains between three extraordinary species. All influenced by a fluke of evolution and something that should never have existed on Earth in the first place. Something we are now finally on the verge of understanding.

It will take more than just one brain to do it. More than just one species. And courage from all three.

Courage in the face of those still trying to stop Clay and Alison before their stranglehold on the world is lost.

But Clay and his team already know the truth. That there is no courage without fear, and no victory without sacrifice.

The Last Monument

One small handwritten letter, sent from a distant corner of the planet and lost in the system for sixty years... is about to change the entire human race.

Outside Denver, Colorado, Joe Rickards stands over a small aircraft wreckage, studying burnt remains still smoldering in a field of freshly fallen investigator for the NTSB, working to carefully roll back the last several hours and identify the cause of the accident.

But this time, he can't.

The details behind this tragedy don't add up. Unlike every other investigation of Joe's career, the facts make no sense. Each new piece of information only makes the accident more mysterious, and more baffling.

Why would a person receive an age-old letter and suddenly disappear into the thick of night...paying to be flown out of a closed airport in the worst possible weather conditions, by a pilot who hadn't had his hand on the stick in years?

With the only surviving relative insisting her grandfather would never have climbed into a small airplane in the first place, even in perfect weather.

A bizarre string of events culminating in a horrible accident unlike anything Rickards has experienced. Leaving his only hope at understanding it in the hands of the victim's sole remaining relative. Beginning with how a mysterious letter could turn up after being lost in the system for sixty years. Sent by someone who should have already been long dead.

A single letter, Joe Rickards is about to discover, with a secret that will change the entire world.

The Desert of Glass

One of mankind's greatest secrets... has been hiding in plain sight for three thousand years.

Half a century ago, an aberration was spotted by one of our earliest satellites, and summarily dismissed as a hardware malfunction. But it was no aberration. And no malfunction. It was an accidental glimpse of something extraordinary, and very old.

Mocked for decades, the man who designed the satellite is now dead. With the system's original data firmly in the hands of former NTSB investigator Joe Rickards and anthropologist Angela Reed.

But the data is only to be shared with one other person besides them: a seventy-five-year-old NASA engineer who was part of the original program.

Joe Rickards is convinced it will lead mankind into darkness.

Angela believes it may be the answer the modern world has been longing for.

And former NASA engineer Leonard Townsend hasn't the slightest idea what he's about to get involved in.

To make matters worse, through a strange bedside confession, a journalist thousands of miles away has just learned that someone else already knows about the satellite's fifty-year-old discovery.

Because they've been secretly using it for years.
