I knew all about Taylor's "leave." He was out in the agricultural canisters, ripped on amitriptyline, doing aerobic exercises to counter his latest bout with clinical depression. One of the occupational hazards of being a surrogate. Taylor and I don't get along. Funny how you usually don't, if the guy's psychosexual profile is too much like your own.

"Hey, Toby, where are you getting all that dope?" The question was ritual. "From Charmian?"

"From your mom, Hiro." He knows it's Charmian as well as I do.

"Thanks, Toby. Get up here to the Heavenside elevator in five minutes or I'll send those Russian nurses down to help you. The male ones."

I just swung there in my hammock and played the game called Toby Halpert's Place in the Universe. No egotist, I put the sun in the center, the lumiary, the orb of day. Around it I swung tidy planets, our cozy home system. But just here, at a fixed point about an eighth of the way out toward the orbit of Mars, I hung a fat alloy cylinder, like a quarter-scale model of Tsiolkovsky 1, the Worker's Paradise back at L-5. Tsiolkovsky 1 is fixed at the liberation point between Earth's gravity and the moon's, but we need a lightsail to hold us here, twenty tons of aluminum spun into a hexagon, ten kilometers from side to side. That sail towed us out from Earth orbit, and now it's our anchor. We use it to tack against the photon stream, hanging here beside the thing the point, the singularity we call the Highway.

The French call it le metro, the subway, and the Russians call it the river, but subway won't carry the distance, and river, for Americans, can't carry quite the same loneliness. Call it the Tovyevski Anomaly Coordinates if you don't mind bringing Olga into it. Olga Tovyevski, Our Lady of Singularities, Patron Saint of the Highway.

Hiro didn't trust me to get up on my own. Just before the Russian orderlies came in, he turned the lights on in my cubicle, by remote control, and let them strobe and stutter for a few seconds before they fell as a steady glare across the pictures of Saint Olga that Charmian had taped up on the bulkhead. Dozens of them, her face repeated in newsprint, in magazine glossy. Our Lady of the Highway.
