Ninety-nine years after going into cryo, Matty wakes up to a world he doesn't know, with no memories of the world—or the man he loves—that he left behind. This new world is full of suspicion and darkness, humanity having moved underground in the aftermath of the mysterious Event.
And as Matty's memories return, along with his beloved Arkady, instead of his life getting easier, he finds his new reality only getting more complicated—and more dangerous.
