2022 Manly Wade Wellman Award (longlist)
After a mysterious global event, six strangers wake up in an underground bunker.
They don't know where they are. Or how much time has passed.
They soon learn that they're part of an experiment to restart the human race.
What they don't realize is that this experiment hides a secret.
And so does the world waiting for them outside.
From the worldwide bestselling author of Departure and Winter World, comes a standalone novel with a twist you've never seen before.
