Cirocco frowned from one picture to the other. Just a lot of little black dots to me. Well, yeah. You can39。s it right there. She indicated an area with her little %er.

They had all learned to stay out of each other39。s forehead as her fingers flew over the keyboard. With each pro gram she called up, the numbers on her screen changed. It had a very close call with Rhea about three million years ago, she noted. It39。s orbit, though perturbations must be a factor. It39。t tell them apart. I was afraid you39。There are ways to explain it. A catastrophic event in the recent past. It Bill39。s toes and was now exploring her left car. She liked that. It had been a memorable journey. Cirocco had loved every centimeter of it。t dare handle them. His delicate touch paid off when he made love. It was matched by his gentle disposition. Cirocco wondered why it had taken her so long to find him. There were three men aboard Ringmaster, and Cirocco had made love to them all. So had Gaby Pla was taller than most of them. She thought it was more in his eyes, which were soft and brown and liquid. And his smile. Those eyes and that smile had done nothing for Gaby, just as Cirocco39。t you think you39。t care. The Science Module of Ringmaster was the finest toy a girl ever had. She loved her work so much she had joined the astronaut corps and graduated at the top of her class so she could watch the stars without an annoying atmosphere, even though she hated to travel. When she was working she noticed nothing else, did not think it odd that Calvin spent almost as much time in SCIMOD as she did, waiting for the chance to hand her a photographic plate or a lens cloth or the keys to his heart. Gene didn39。t receiving. He just grinned with that boyish, touslehaired Aryan ideal face and talked about flying. He was to be the pilot of the Satellite Excursion Module when the ship reached Saturn. Cirocco liked flying, too, but there came a time when a woman wanted to do something else. But eventually Calvin and Cirocco got what they had wanted. Soon after, neither wanted it anymore. Cirocco didn39。 neither of them talked about it, but it was obvious that it worked only passably at best. Calvin continued to see her, but she saw Gene, too. Gene had apparently been waiting for Cirocco to stop chasing him. As soon as she did, he began to sidle up and breathe heavily in her ear. She didn39。 Gene would have been astonished to learn where he fell on her scale of one to ten. Bill had happened almost by accidentthough she had since learned that few accidents happened around Bill. One thing led to another, and now they were about provide a pornographic demonstration of Newton39。s outermost moonin 1905. He named it Themis, and no one ever saw it again. Calvin points out that five of the Saturnian moons are already named after the Titans of Creek myth (which is a special interest of his。s mind is appeased. Themis has things in mon with the moon Pickering thought he saw, but Gaby is not convinced he actually sighted it. (If he did, she would not be listed as its discoverer. But to be fair, it seems too small and dim to be seen in even the best Lunar scopes.) Gaby is formulating a cataclysmic theory of Themis 39。m sorry to disturb you.That39。t busy. We have something up here you should see. Be right up. She thought it was August. Cirocco had worked on keeping them straight since twins generally resent being mistaken for each other. She had gradually realized that April and Aug
