Chapter One: 11:56 p.m.
Eyes mark the shape of the city.

Through the eyes of a high-flying night bird, we take in the scene from midair. In our broad sweep, the city looks like a single gigantic creature--or more like a single collective entity created by many intertwining organisms. Countless arteries stretch to the ends of its elusive body, circulating a continuous supply of fresh blood cells, sending out new data and collecting the old, sending out new consumables and collecting the old, sending out new contradictions and collecting the old. To the rhythm of its pulsing, all parts of the body flicker and flare up and squirm. Midnight is approaching, and while the peak of activity has passed, the basal metabolism that maintains life continues undiminished, producing the basso continuo of the city's moan, a monotonous sound that neither rises nor falls but is pregnant with foreboding.

Our line of sight chooses an area of concentrated brightness and, focusing there, silently descends to it--a sea of neon colors. They call this place an "amusement district." The giant digital screens fastened to the sides of buildings fall silent as midnight approaches, but loudspeakers on storefronts keep pumping out exaggerated hip-hop bass lines. A large game center crammed with young people; wild electronic sounds; a group of college students spilling out from a bar; teenage girls with brilliant bleached hair, healthy legs thrusting out from micromini skirts; dark-suited men racing across diagonal crosswalks for the last trains to the suburbs. Even at this hour, the karaoke club pitchmen keep shouting for customers. A flashy black station wagon drifts down the street as if taking stock of the district through its black-tinted windows. The car looks like a deep-sea creature with specialized skin and organs. Two young policemen patrol the street with tense expressions, but no one seems to notice them. The district plays by its own rules at a time like this. The season is late autumn. No wind is blowing, but the air carries a chill. The date is just about to change.

We are inside a Denny's.

Unremarkable but adequate lighting; expressionless decor and dinnerware; floor plan designed to the last detail by management engineers; innocuous background music at low volume; staff meticulously trained to deal with customers by the book: "Welcome to Denny's." Everything about the restaurant is anonymous and interchangeable. And almost every seat is filled.

After a quick survey of the interior, our eyes come to rest on a girl sitting by the front window. Why her? Why not someone else? Hard to say. But, for some reason, she attracts our attention--very naturally. She sits at a four-person table, reading a book. Hooded gray parka, blue jeans, yellow sneakers faded from repeated washing. On the back of the chair next to her hangs a varsity jacket. This, too, is far from new. She is probably college freshman age, though an air of high school still clings to her. Hair black, short, and straight. Little makeup, no jewelry. Small, slender face. Black-rimmed glasses. Every now and then, an earnest wrinkle forms between her brows.

She reads with great concentration. Her eyes rarely move from the pages of her book--a thick hardback. A bookstore wrapper hides the title from us. Judging from her intent expression, the book might contain challenging subject matter. Far from skimming, she seems to be biting off and chewing it one line at a time.

On her table is a coffee cup. And an ashtray. Next to the ashtray, a navy blue baseball cap with a Boston Red Sox "B." It might be a little too large for her head. A...
