The Atlantis Plague: A Thriller (The Origin Mystery, Book 2)

The Atlantis Plague is the second book in The Origin Mystery, the blockbuster trilogy that has sold a million copies in the US, is being translated into eighteen languages, and is in development to be a major motion picture.


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 the Atlantis Plague doesn’t 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 humanity’s last hope is to find a cure, and 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. Kate’s journey takes her across the barren wastelands of Europe and northern Africa, but it’s 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 human race must remain as one. All other roads lead to ruin.”
– The Orchid Alliance

“Evolution is inevitable. Only fools fight fate.”
– Immari International

THE ATLANTIS PLAGUE is a story of human survival and perseverance in the face of extinction. This global adventure takes readers back into the world of The Origin Mystery, which began with A.G. Riddle’s debut sci-fi thriller, THE ATLANTIS GENE. THE ATLANTIS PLAGUE delivers the same kind of little-known science and history readers applauded in THE ATLANTIS GENE and deepens the core mystery many can’t stop talking about. The series is currently in development at CBS Films to be a major motion picture.

All three books in the trilogy are now available:
Book 1: The Atlantis Gene —
Book 2: The Atlantis Plague —
Book 3: The Atlantis World —

  1. Wonderful Sequel! I loved the story from the first book, but I struggled with the writing style and character development. This sequel expands the original story, ties up some loose ends, and the best surprise for me was how much better the character development was. The book can get fairly technical sometimes, but I like that kind of science fiction. Some of the tangents can get annoying, and the extent of the fantastical twists gets fairly complex. Ultimately, I was able to follow along enough to really…

  2. Fantastic sequel! If you haven’t read book one of this series, you need to do so immediately. The follow-up second book is just as good – perhaps even better than the first. Well developed characters, stunning plot twists, history, genetics, science fiction – its all here. Believe me, you won’t be able to put it down.

  3. Wonderful and complex! I have thoroughly enjoyed reading both The Atlantis Gene and Plague, and eagerly await the next installation. The story is quite exciting, and most definitely qualifies as an “edge of your seat thriller,” but is also quite complex and requires frequent stops to ponder the theories. I did get lost a couple of times, but I just had to read on and was rewarded with some resolution – although I have concluded that I am definitely not smart enough to be an Atlantean – and could quite possibly be one…
