The Extinction Trials

An Amazon Editor's Pick for Best Books of the Month.
After a mysterious event, six strangers wake up in an underground bunker.
They don't know how much time has passed. Or where the bunker is located.
They seem to be part of a vast scientific experiment aimed at restarting the human race after a global catastrophe—a program called The Extinction Trials.
What they don't realize is that The Extinction Trials hides a secret.
And so does the world outside.
From the bestselling author of Departure and Winter World, comes an epic standalone novel with a twist you'll never forget.

Amazon.com Review
An Amazon Best Book of December 2021: Riddle is a master of rethinking humanity’s near future, and The Extinction Trials delivers more of the page-turning surprises that his readers have come to expect from previous books such as Winter World and The Atlantis Gene. As the book opens, the Change is upon humanity, and only a few people are saved from the cataclysm. These folks awaken to learn that they are in the Extinction Trials—an experiment designed to figure out scenarios that can restart the human race. I always appreciate that Riddle’s characters try to do the right thing against heavy odds and in the midst of a corkscrewing reality, and I recommend him as a great match for those who enjoy Andy Weir, Martha Wells, or Arkady Martine. —Adrian Liang, Amazon Books
