The Origin Mystery Books in Order

The Origin Mystery trilogy starts with a handful of strange events that shouldn’t be connected: a structure discovered deep inside an Antarctic iceberg, an autism research trial in Jakarta, and a counterterrorism analyst watching encrypted messages spike and then go silent. Before long, it’s clear they are all pieces of the same puzzle.

The stakes turn out to be nothing less than the future path of human evolution.

At the center of that puzzle is Dr. Kate Warner, a geneticist whose work with children on the autism spectrum has begun to show impossible results. When her patients are kidnapped and her Jakarta clinic is attacked, she is forced onto the run with David Vale, an agent from the clandestine group Clocktower. Together they begin to uncover hints of an Atlantis Gene dormant inside human DNA.

Their enemies are the Immari, a secret society that traces its origins back to the last ice age and a catastrophe that nearly wiped out Homo sapiens. In The Atlantis Gene, the Immari are preparing a new extinction event, convinced that only a drastic culling will allow the most resilient humans to survive the return of an ancient threat.

In The Atlantis Plague, that plan erupts into the open. A lethal pandemic races across the globe, killing some and radically altering others. Nations collapse, borders vanish, and Kate’s hunt for a cure takes her through quarantined cities, desert strongholds, and buried Atlantean facilities. Every step reveals more about the true history of humanity and the price paid for survival seventy thousand years ago.

The Atlantis World pushes the story beyond Earth. Following the trail of Atlantean technology, Kate, David, and their allies travel to orbiting stations and distant outposts, piecing together what really happened to the civilization beneath the ice and what kind of enemy it was running from. The scale widens from a single outbreak to a struggle that spans galaxies and deep time.

Across all three books, Riddle balances rapid‑fire action with puzzles, flashbacks, and big questions about evolution, free will, and what better humans might look like. Expect globe‑trotting set pieces, buried ships and ancient labs, and a core relationship between Kate and David that anchors the wilder twists. It’s a series that rewards being read straight through from The Atlantis Gene to The Atlantis World.
