After taking part in a science experiment that should have only lasted hours, Alex wakes to a world very different from the one he left behind. Everyone he's ever known is gone, and what's left of America lies in ruin, but those are the least of his worries. Relentlessly pursued by powerful forces wielding advanced technology, and forced to contend with the dangerous inhabitants of this new land, Alex must do everything he can to survive. At least he won't be facing these challenges alone, but his new friends be enough to protect him from what the future holds?
