Free Aurora in Four Voices by Catherine Asaro, Steven H Silver, Joe Bergeron Page A

a dusky hue, full of rosy blooming health. None of the Dreamers spared her a second look, but Jato thought she was lovely.
    She sat down — and the server showed up to take her order. Irked, Jato got up and headed for the laser bar, intending to insist they serve him. Reaching it, however, was no simple feat. The Dome's floor consisted of nested rings, each slowly rotating in one direction or the other. The text he had found in the library described some business about "mapping coefficients in quantum superpositions onto ring velocities." All he knew was that it took a computer to coordinate the motion so patrons could step from one ring to another without falling. Dreamers carried it off with grace, but he had never mastered it.
    He managed to reach the dance floor, a languid disk turning in the Dome's center. Dancers drifted away from him, slim and willowy, silver-eyed works of art. On the other side, he ventured into the rings again and was soon being carried this way and that. Each time he neared a hovertable occupied by Dreamers, it floated away on cushions of air. He wished just once someone would look up, admit his presence, give a greeting. Anything.
    Meanwhile, the server brought the spacer her drink, which was a LaserDrop in a wide-mouthed bottle. Tiny lasers in the glass suffused the drink with color: helium-neon red, zinc-selenium blue, sodium yellow. Drink in hand, she settled back to watch the dancers.
    Jato quit pretending it was the bar he wanted and headed for the spacer. But whenever he neared the ring with her hovertable, people and tables that had been drifting away suddenly blocked his path. The spacer meanwhile finished her drink, slid a payment chip into the table slot, and headed for the door. He started after her — and the drink server appeared, blocking the way, his back to Jato, his tray of laser-hued drinks held high.
    Jato scowled. He had always been long on patience and short on words. But even the most stoic man could only take so much. He put his hand against the server's back and pushed, not hard, just enough to make the fellow move. The server stumbled and his tray jumped, rum splashing out of the jars in plump drops. Even then, no one looked at Jato, not even the server.
    He made it to the door without pushing anyone else. Outside, lamps lit the area for a few meters, but beyond their radiance, night reigned under a sky rich with stars. Jato strode away from the Dome, his fists clenched. He didn't want to give them the satisfaction of seeing their treatment provoke him.
    The Dome was on the city outskirts, near the edge of a large plateau where the Dreamers had built Nightingale. The Giant's Skeleton Mountains surrounded the plateau, falling away from it on three sides and rising in sheer cliffs on the fourth, here in the north. The northern peaks piled up higher and higher in the distance, until they become a jagged line against the star-dazzled sky.
    The Dreamers claimed they built Nightingale as a challenge: can you create beauty in so forbidding a place? This was the reason they gave. Jato had heard others put forth, but the Dreamers denied them.
    Although his past attempts at convincing spacers to smuggle him offplanet had failed, he never gave up. In the distant shadows, he saw the spacer climbing the SquareCase, a set of stairs carved into a cliff. The first step was one centimeter high, the second four, the third nine, and so on, their heights increasing as the square of integers. The first twenty ran parallel to the cliff, but then they turned at a right angle and stepped into the mountains, rising taller and taller, until they became cliffs themselves, too high, too dark, and too distant to distinguish.
    By the time he reached the first step of the SquareCase, the spacer was climbing the tenth, about the height of her waist. She sat on it, half hidden in the dark while she watched him. He approached slowly and stopped on the ninth step.
    "Can I do something for you?" she
