His debut novel, The Atlantis Gene, is the first book in The Origin Mystery, the trilogy that has sold a million copies in the US, is being translated into 19 languages, and is in development at CBS Films to be a major motion picture. The trilogy will be in bookstores (in hardcover and paperback) around the world in 2015.

His recently released fourth novel, Departure, follows the survivors of a flight that takes off in 2014 and crash-lands in a changed world. The hardcover will be published by HarperCollins in the fall of 2015, and 20th Century Fox is developing the novel for a feature film.

Riddle grew up in a small town in the US (Boiling Springs, North Carolina) and graduated from UNC-Chapel Hill.

Title
Description
01
Around the world, a deadly outbreak spreads.

The CDC and WHO race to stop it, but they soon learn that this pandemic hides a dark secret. It may be the start of a scientific experiment that could alter the human race forever--and reveal a shocking truth about our future.

Experience the groundbreaking novel that will change everything you think you know about pandemics--and how to survive one.

“Reads like a superior collaboration between Dan Brown and Michael Crichton.”
The Guardian

Now an Amazon Charts and Wall Street Journal bestseller.


A hundred miles north of Alaska, a US Coast Guard vessel discovers a sunken submarine at the bottom of the Arctic Ocean. It has no national identification and doesn’t match the records of any known vessel. Deep within, researchers find evidence of a scientific experiment that will rewrite our basic understanding of the human race.

In Atlanta, Dr. Peyton Shaw is awakened by the phone call she has dreaded for years. As the CDC’s leading epidemiologist, she’s among the first responders to outbreaks around the world. It’s a lonely and dangerous job, but it’s her life—and she’s good at it. This time, she may have met her match.

In Kenya, an Ebola-like pathogen has infected two Americans. One lies at death’s door. With the clock ticking, Peyton assembles her team and joins personnel from the Kenyan Ministry of Health and the WHO. What they find in the remote village is beyond their worst fears. As she traces the origin of the pathogen, Peyton begins to believe that there is more to this outbreak—that it may be merely the opening act in a conspiracy with far reaching consequences.

In Berlin, Desmond Hughes awakens in a hotel room with no memory of how he got there or who he is. On the floor, he finds a dead security guard from an international pharmaceutical company. His only clue leads him to Peyton Shaw—a woman who seems to know him, but refuses to tell him how. With the police searching the city for him, Desmond desperately tries to piece together what happened to him. To his shock and horror, he learns that he may be involved in causing the outbreak—and could hold the only key to stopping it.

As the pathogen spreads around the world, Peyton and Desmond race to unravel the conspiracy behind the pandemic—and uncover secrets some want to keep buried. With time running out, they face an unimaginable decision.

An Extended Look At The Atlantis Gene

70,000 years ago, the human race almost went extinct.
We survived, but no one knows how.
Until now.

The countdown to the next stage of human evolution is about to begin, and humanity might not survive this time.


Off the coast of Antarctica, a research vessel discovers a mysterious structure buried deep within an iceberg. It has been there for thousands of years, and something is guarding it. Could it be the fabled city of Atlantis? Or is it something more dangerous?

At the same moment, in Jakarta, Indonesia, a brilliant geneticist named Kate Warner has just discovered a breakthrough treatment for autism. Or so she thinks. What she has found is far more deadly—for her and for the entire human race. Her work could unleash the next stage of human evolution. It might also hold the key to unlocking the mysterious structure off the coast of Antarctica.

On the other side of Jakarta, Agent David Vale is racing to uncover a conspiracy with far-reaching implications. But he’s out of time. His informant inside the conspiracy is dead. His own organization has been infiltrated—and his enemy has turned the hunt on him. Now he’s on the run. But when he receives a coded message related to an imminent attack, he risks everything to save the one person that can help him stop it: Dr. Kate Warner.

Together, Kate and David race to unravel a global conspiracy and learn the truth about the Atlantis Gene... and human origins. Their journey takes them to the far corners of the globe and into the secrets of their pasts. Their enemy is close on their heels and will stop at nothing to obtain Kate’s research and force the next stage of human evolution—even if it means killing 99.9% of the world’s population. David and Kate can stop them... if they can trust each other. And stay alive.
03
A new ice age... and a shocking discovery...
will change humanity forever.


In the near future, a new ice age has begun.

Humanity stands on the brink of extinction.

Desperate for answers, scientists send probes into the solar system to take readings. Near Mars, a probe spots a mysterious object drifting toward the Sun. Is it the cause of the ice age? Or could it be our only hope of survival?

With time running out, NASA launches an international mission to make contact with the object. But it isn’t what anyone thought. In the dark of space, alone, the team makes a shocking discovery that will change the course of human history—and possibly end it.
04
A wild propulsive adventure full of hairpin twists, Departure weaves together power, ambition, fate, memory, and love. The world's past and future rests in the hands of five unwitting strangers. En route to London from New York, Flight 305 suddenly loses power and crash-lands in the English countryside, plunging a group of strangers into a mysterious adventure that will have repercussions for all of humankind. Struggling to stay alive, the survivors soon realize that the world they've crashed in is very different from the one they left. But where are they? Why are they here? And how will they get back home? Five passengers seem to hold clues about what's really going on: writer Harper Lane, venture capitalist Nick Stone, German genetic researcher Sabrina Schröder, computer scientist Yul Tan, and Grayson Shaw, the son of a billionaire philanthropist.
As more facts about the crash emerge, it becomes clear that some in this group know more than they're letting on, answers that will lead Harper and Nick to uncover a far-reaching conspiracy involving their own lives. As they begin to piece together the truth, they discover they have the power to change the future and the past-to save our world... or end it.
05
A code hidden in the human genome will reveal the ultimate secret of human existence.

And could hold humanity's only hope of survival.


Genome concludes The Extinction Files, the two-book series that began with Pandemic. It's a race against time—and an exploration into the deepest mysteries of human existence (with a twist at the end you'll never see coming).

An Extended Look At Genome

In 2003, the first human genome was sequenced. It was a breakthrough of historic proportions, but only one scientist knows the full truth of what lies buried in our DNA. That secret will change everything we thought we knew about our past. And our future.

Dr. Paul Kraus has spent his career searching for what he calls humanity's lost tribes--human ancestors who have gone extinct. When Kraus compares the DNA samples of the lost tribes with our own, he discovers a pattern of changes. A code. He believes he knows what the code is, but the technology doesn't exist to fully decode it. To protect the secret, Kraus hides his work and disappears.

For years, the secret remains buried. When Kraus dies mysteriously, his work is lost forever.

Now the technology exists to finally unravel the code buried in the human genome. The race to find Kraus's research has begun, and one group will do anything to find it.

Dr. Peyton Shaw and her mother have obtained part of Kraus's research--and a cryptic message that could lead to the remaining pieces. They soon learn that finding those pieces may be more dangerous than anyone imagined. But there's no choice. His work is the key to stopping a global conspiracy--and an event that will change humanity forever.

The ultimate secret, buried in the human genome, will change our very understanding of what it means to be human. For Peyton, finding it may come at an incredible price. She must weigh the lives of strangers against those she loves: Desmond Hughes and her mother. With time running out, Peyton makes a fateful choice--one that can never be undone.

An Extended Look at The Atlantis Plague

In Marbella, Spain, Dr. Kate Warner awakens to a horrifying reality: the human race stands on the brink of extinction. A pandemic unlike any before it has swept the globe. Nearly a billion people are dead—and those that the Atlantis Plague does not kill, it transforms at the genetic level. A few rapidly evolve. The remainder devolve.

As the world slips into chaos, radical solutions emerge. Industrialized nations offer a miracle drug, Orchid, which they mass produce and distribute to refugee camps around the world. But Orchid is merely a way to buy time. It treats the symptoms of the plague but never cures the disease.

Immari International offers a different approach: do nothing. Let the plague run its course. The Immari envision a world populated by the genetically superior survivors—a new human race, ready to fulfill its destiny.

With control of the world population hanging in the balance, the Orchid Alliance and the Immari descend into open warfare. Now the last hope for humanity is to find a cure. Kate alone holds the key to unraveling the mystery surrounding the Atlantis Plague. The answer may lie in understanding pivotal events in human history—events when the human genome mysteriously changed. Her journey takes her across the barren wastelands of Europe and northern Africa, but it is her research into the past that takes her where she never expected to go. She soon discovers that the history of human evolution is not what it seems—and setting it right may require a sacrifice she never imagined.

The Atlantis Gene (The Origin Mystery #1)

The Greatest Mystery Of All Time…
The History Of Human Origins…
Will Be Revealed....

70,000 years ago, the human race almost went extinct!
We survived, but no one knows how?
Until now...
The countdown to the next stage of human evolution is about to begin, and humanity may not survive this time...

The Immari are good at keeping secrets. For 2,000 years, they have hidden the truth about human evolution. And they’ve searched for an ancient enemy - a threat that could wipe out the human race. Now the search is over.

Off the coast of Antarctica, a research vessel has discovered a mysterious structure buried deep in an iceberg. It’s been there for thousands of years, and it isn’t man made. The Immari think they know what it is, but they aren’t taking any chances. The time has come to execute their master plan: humanity must evolve or perish. In a lab in Indonesia, a brilliant geneticist may have just discovered the key to their plan.

Four years ago, Dr. Kate Warner left California for Jakarta, Indonesia to escape her past. She hasn’t recovered from what happened to her, but she has made an incredible discovery: a cure for autism. Or so she thinks. What she’s found is actually far more dangerous. Her research could rewrite human history and unleash the next stage of human evolution. In the hands of the Immari, it would mean the end of humanity as we know it.

One man has seen pieces of the Immari conspiracy: Agent David Vale. But he’s out of time to stop it. His informant is dead. His organization has been infiltrated. His enemy is hunting him. But when he receives a cryptic code from an anonymous source, he risks everything to save the only person that can solve it: Dr. Kate Warner.

Now Kate and David must race to unravel a global conspiracy and learn the truth about the Atlantis Gene… and human origins. Their journey takes them to the far corners of the globe and into the secrets of their pasts. The Immari are close on their heels and will stop at nothing to find the Atlantis Gene and force the next stage of human evolution - even if it means killing 99.9% of the world’s population. David and Kate can stop them… if they can trust each other. And stay alive.
