THE ELEVATOR WAS A HOLLOW CYLINDER TEN STORIES HIGH, WITH A glass dome at each end, one aimed up at the Eye and the other aimed down at Earth. The floors beneath those domes were made of glass, so that the light shone through from end to end. The outer walls were windowless and heavily shielded against cosmic radiation, but on the inside, the cabins and lounges had windows onto the atrium. Or at least the more expensive cabins did; Kath Two’s was at the periphery, hard up against the outer wall, with no windows other than a tiny porthole onto a ring-shaped corridor. Which was fine with her. At the beginning of the journey they were in near weightlessness, but as the days went on, gravity would increase, reaching one normal gee at Cradle. She could tell when she woke up that she had not slept for long, since gravity was still quite faint, perhaps comparable to what had once existed on the moon.
