Binary was a banded orange giant, bigger than Jupiter, and much warmer. Jinx was six times as big as Earth, with a gravity of one point seven eight, and with a period of rotation more than four days long. Of all the factors which had shaped Jinx, the most important had been its lack of radioactive materials. For Jinx was solid all through its rocky lithosphere and halfway to the center of its nickel-iron core.

Long ago- before even his time, Kzanol's time- Jinx had been much closer to Binary. So close that the tides had stopped her spin and pulled her into an egg shape. Later, those same tides had pushed her outward. Not unusual. But, though the atmosphere and ocean assumed a more spherical shape, Jinx did not. The body of the moon was still egg shaped.

Jinx was an Easter egg, banded in different colors by the varying surface pressures.

The ocean was a broad ring of what must be extremely salty water running through the poles of rotation. The regions which the colonists called the Ends, marked by the points nearest to and furthest from Binary, were six hundred miles «higher» than the ocean: six hundred miles further from the moon's center of mass. They stuck right out of the atmosphere. In the photographs masered in from the first expedition, the Ends had shown bone white, with a tracery of sharp black shadows. Further from the Ends the shadows disappeared beneath the atmosphere, and clouds began to appear. The clouds became thicker and thicker, with brown-and-gray earth showing more and more rarely, until suddenly the clouds were in full control. The ocean was forever hidden beneath a band of permanent fleecy cloud thousands of miles wide. At sea level the air was terrifically dense, with a constant temperature of two hundred and seventy degrees Fahrenheit.

The colony of Sirius Mater was on the Eastern continent, three thousand miles east of the ocean, a triangle of cultivated land and inflatable buildings at the fork of two rivers. The first colonists had picked a landing place with a high surface pressure, knowing that the denser atmosphere would help protect them from the temperature changes during the long days and nights, and from the ultraviolet scourge of blue-white Sirius A. Sirius Mater now boasted a population of almost two hundred punsters of all ages…

"Good," said Garner. "Then I won't have to explain anything. Can I borrow the phone, Lloyd?"

"Sure." Lloyd hooked a thumb at one wall.

The phone screen was a big one; it covered half the wall. Luke dialed thirteen quick motions of the forefinger. In a moment the screen cleared to reveal a slender young woman with wavy brunette hair.
