One rain-swept Sunday night when he was twenty years old, on his way back to college after a weekend with his family, Joey Shannon took the wrong highway - and from that moment, nothing ever went right for him again. Now, exactly twenty years later, on another rain-swept night, Joey finds himself at the same crossroads, looking down the road never taken. Which is odd. Because that road no longer exists. A superhighway replaced it nearly twenty years ago, and the old state route - which had crossed a web of perpetually burning, abandoned coal mines - was condemned as too dangerous and was torn up. But now the highway is exactly as it was on that long-ago night, and when Joey turns on to it, he begins an eerie, terrifying journey toward a truth so dark and stunning that it will change everything he believes about himself, his past, and the nature of life.
