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.
