Our narrator is Sean. When he was a teenager an accident (or maybe "accident") with a gun left him disfigured. He leads an isolated life as an adult, partially filling his time and making a little money running a play-by-mail adventure game called the Trace Italian, a game that he created while recovering from his injuries in the hospital as a teenager. In the game, players find themselves in a post-nuclear apocalypse society, trying to save themselves by finding and getting into the Trace Italian, a safe and complicated series of chambers somewhere underground in the middle of Kansas. We learn that the adult Sean is being sued because two players of his game, a young couple, took the play too literally and one died and the other nearly died somewhere in the wilds of Kansas.
While that covers most of the plot of the novel, the real action is happening inside Sean's head as we move back and forth between his pre- and immediately post-accident teenage self and the man he has become. The accident and his isolation in some ways have frozen him in time and the feelings that brought him into this state are never that far from the surface. As the book moves on, we see Sean interact with his nurse, an old friend, his mother, and (hilariously) some teenage hoodlums out behind the liquor store. All of these interactions serve to deepen Sean's character and, to me at least, highlight how he is ultimately happy in his isolation. There are no pat answers or neatly tied up endings here, but some nice character development and a very real and effective world.

This book (his first novel, although he's also written
