The end of the world didn't arrive with war, or zombies, or plagues.  No, for Ryan Thatcher the end of the world began with silence.  Complete and utter silence, as seemingly everyone but him disappeared.  In a world of isolation, it wasn't until a month later that he learns that he's not alone here, where he'd been left behind. There are other things that crawl in the dark. That skulk just out of sight, until night descends. In a world of silence, only their whispers can be heard. And until Ryan can solve the mystery of where everyone else had gone, he must first learn how to survive them.
