But why not? he wondered. Did everything have to be done on her terms? Where he came from, it was perfectly all right to make the offer, so long as one was prepared to be turned down. He had no idea how they did such things in the Coven, except to know that the situation could never arise between a man and a woman. Perhaps she was as confused as he, socially.

So when she stopped rubbing his back, he turned, put one hand gently to her cheek, and kissed her on the lips. When he drew away, she looked puzzled.

"What was that for?"

"Because I like you. Don't you kiss in the Coven?"

"Of course we do." She shrugged. "How strange. I hadn't realized it, but you smell different. Not actually unpleasant, but different." She turned from him and dived awkwardly toward the shore. She windmilled her arms and thrashed her legs without really getting anywhere and soon had to stand up and spit water.

Chris sank until the water lapped at his chin. He had never been rebuffed in quite that way before. He knew she had not been aware she was turning him down, but it was still deflating.

"I fell into the river when I got here," she said as they slogged through the shallow water toward the beach. "I did something to get to shore because I knew I had to. But I can't put it all together now."

"You probably didn't have far to go, or the current was helping you."

"Can you show me now?"

"Maybe later."

At the beach he tossed her the soap again. She stood with her feet in the water and washed her lower body. He watched her, wishing there were more light so he could finally get a better look at the tattoos. Abruptly, he decided he had better sit down.

"What's the matter?"

"Nothing."

"I saw what was happening." She frowned at him. "Don't tell me you thought you could-"

"It's called the gallant reflex, okay?" Chris was embarrassed and annoyed. "Reflex. I didn't plan to assault you or anything. You just look very, very good standing there, and ... who could help it?"

"You mean that just by looking at me ..." She covered herself with a hand and a forearm. To Chris, it made her look prettier than ever. "I didn't realize that's what my mother meant, or maybe I thought it was another mistake."

"Why didn't you realize? You seem to think we're so different. I'm just like you. Can't you get aroused by looking at someone sexually desirable?"

"Well, sure, but it didn't occur to me that a man-"

"Don't make it into such a tremendous distinction. We have a lot of things in common, whether you like it or not. We both erect, both have orgasms-"

"I'll bear it in mind," she said, tossed him the soap, scooped up her clothes, and hurried off down the beach.Chris worried that he might have killed a budding friendship. He did like her, almost in spite of himself. Or in spite of her. He wanted to be her friend.

A little later he wondered if she had left because of anger. Going back over the conversation, he realized that the point she had chosen to leave could be given another interpretation.

He did not think Robin would be too comfortable with the idea that he was like her. Or, conversely, that she was like him.

The completed raft would not have won any prizes in a boat show, but it was a marvel from the standpoint of size alone, considering the time it had taken to build it. It slid down the ramp which had been its construction site and hit the water with a mighty splash. Chris joined the Titanides in cheering. Robin was yelling, too. They had both had a hand in the finishing stages. The Titanides had shown them how to handle the glue and let them set deck planks in place while the railings were being installed.

It had ample room for the eight of them. There was a small cabin near the bow, large enough to bunk all the humans at once, and a canopy that could be hung to keep the rain off the Titanides. A mast amidships supported a silver Mylar sail with a minimum of rigging. Steering was done with a long tiller. Just aft of the mast was a circle of stones to support the cooking fire.

Gaby, Chris, and Robin gathered by the gangplank while the Titanides carried aboard saddlebags, provisions they had gathered near the beach, and heaps of firewood. Cirocco had already gone aboard and installed herself at the bow, gazing at nothing.

"They want me to name it," Gaby said to Robin. "Somehow I've gotten the reputation around here as the namer of names. I pointed out that we'll be using this raft for only eight days at the most, but they think every ship has to have a name."

"It seems appropriate," Robin said.

"Oh, you think so? Then you name it."

Robin thought for a moment, then said, "Constance. Is that all right, to name a ship after-"

"That's fine. A lot better than the first boat I sailed in here."

For several kilometers it was possible to propel Constance with long poles. This was fortunate because the wind had departed along with the rain. Everyone but Cirocco lent a hand. Chris enjoyed the hard work. He knew he was not moving the boat nearly so much as the Titanides, but it felt good to be contributing. He put his back into it until the poles would no longer touch bottom. At that point four oars were rigged, and they took shifts as galley slaves. It was even harder than the poling. After two hours at the oars Robin suffered a violent seizure and had to be taken into the cabin.

During one of his rest periods Chris went around the cabin and found that Cirocco had abandoned her post, presumably to sleep.

He stretched out on his back and felt the muscles protest. The night sky of Rhea was like nothing he had ever dreamed. In Hyperion, on a clear day, the sky was a uniform yellow blur, unguessably high. Only by following the sweep of the central vertical cable to where-as a mere thread-it penetrated the Hyperion Window could one really define where the solid sky was. Even then one had to keep it firmly in mind that the cable was five kilometers in diameter and not the slim spindle into which perspective and the eye's timid bias transformed it.

Rhea was different. For one thing, Chris was closer to the central Rhea vertical cable than he had ever been to Hyperion's great column. A black shadow that leaped from the sea, it dwindled rapidly and kept rising and rising until it vanished completely. To each side of it were the north and south verticals, improperly named because they both angled toward the center, though not nearly so much as the ones behind him, to the west. The cables vanished because of the darkness, but more important, because Rhea did not have a window arching over it. Rhea lived in the shadow of the vast trumpet-shaped mouth known as the Rhea Spoke.

Had he not known its size and shape from pictures, Chris would never have discovered its true geometry. What he could see was a dark, wide oval high overhead. In reality, it was more than 300 kilometers above the sea. Around the edge of that mouth was a valve that could close like the iris of an eye, isolating the space above it from the rim. It was now wide open, and he could see up into a dark, oblate cylinder the upper end of which, he knew, was another 300 kilometers away, where another valve led to the hub. He could not see that far, through that much dark air. But what he could see resembled the barrel of a gun that might have used planetoids for projectiles. It was aimed right at him, but the threat was so overblown he could not take it seriously.

He knew that between the lower valve and the radius of the Hyperion Window-a vertical distance of about a hundred kilometers-the spoke flared like the bell of a horn until it became one with the relatively thin arch of roof that stretched over the daylight areas on each side of Rhea. Try as he might, he could not see that flaring, though it had been discernible from Hyperion. Another trick of perspective, he concluded.
