Imagine you're in an airport boarding lounge, or the waiting room at virtually any train station or bus terminal in the Western world. Maybe you commute to work or school by subway. It doesn't matter. Look around. Somewhere in there, among hundreds of fellow travelers, lurks the shade of a tall, lanky man in a Red Sox gimme cap. Maybe they brought him with them, or bought him at a newsstand after swiping through the turnstile. Maybe they downloaded him, seemingly out of thin air, and he's hiding on an iPad or a Kobo. He may even be lying open in someone's lap, real words on a real page. However he appears, though, chances are he's there. Somewhere.
