can be restored to full functions again within a fraction of a second. Of course, with the embryos we have to be able to put them immediately in a liquid growing solution and hook them up to artificial yolks or placentas, so we can't restore very many at a time."
"In order to carry with you enough samples to restore a significant amount of the flora and fauna most likely to have been killed off on Earth, how much equipment would it take?" asked Nafai.
"How much? A lot-a huge amount. A caravan."
"But what if you had to choose the most significant ones-the most useful birds, the most important animals, the plants we most need for food and shelter."
"Then any size would do," said Shedemei. "You just prioritize-if you have only one camel to carry it, then that's how many you take-two drycases per camel. Plus a camel to carry each set of restoration equipment and materials."
"So it could be done," said Nafai triumphantly.
"You believe the Oversold will send you to Earth?" asked Shedemei.
"We believe it's the most important thing going on right now in the entire world of Harmony," said Nafai.
"My dream?"
"Your dream is part of it," said Luet. "So is mine, I think." She told Shedemei her dream of angels and diggers.
"It sounds plausible enough as a symbol of a world where new-life forms have evolved," said Shedemei. "What you're forgetting is that if your dream comes from the Oversold, it can't possibly be literally true."
"Why not?" asked Luet. She seemed a little offended.
"Because how would the Oversoul know what's happening on Earth? How would it see a true picture of any species there? The Earth is a thousand lightyears away. There has never been an electromagnetic signal tight and true enough to carry significant transmissions that distance. If the Oversoul gave you that dream, she's only making it up."
"Maybe she's guessing," said Hushidh.
"Maybe she's only guessing about the need for Shedemei's seeds and embryos," said Nafai. "But we must still do what the dream commands. Shedemei must collect these seeds and embryos, and prepare to take them to Earth with us."
Shedemei looked at them in bafflement. "I came to tell Aunt Rasa a dream, not abandon my career on a mad impossible journey. How do you think you're going to Earth? By cloud?"
"The Oversoul has said we're going," said Nafai. "When the time comes, the Oversoul will tell us how."
"That's absurd," said Shedemei. "I'm a scientist. I know the Oversoul exists because our submissions are often transmitted to computers in faraway cities, something that can be done in no other way. But I've always assumed that the Oversoul was nothing more than a computer controlling an array of communications satellites."
Nafai looked at Luet and Hushidh in consternation. "Issib and I struggled to figure that out," he said, "and Shedemei knew it all along."
"You never asked me," said Shedemei.
"We would never have spoken to you," said Nafai. "After all, you're Shedemei"
"Just another teacher in your mother's house," said Shedemei.
"Yes, like the sun is just another star in the sky," said Nafai.
Shedemei laughed and shook her head. It had never occurred to her that the young ones would hold her in such awe. She enjoyed knowing it-it felt good to think that someone admired her-but it also made her feel faintly shy and exposed. She had to live up to this image that they had of her, and she was nothing more than a hardworking woman who had been disturbed by a dream.
"Shedemei," said Hushidh, "whether it seems possible or not, the Oversoul is asking us to prepare for this voyage. We would never have dreamed of asking you, but the Oversoul has brought you to us."
"Coincidence brought me to you."
"Coincidence is just the word we use when we have not yet discovered the cause," said Luet. "It's an illusion of the human mind, a way of saying, 'I don't know why this happened this way, and I have no intention of finding out.' "
"That was in another context," said Shedemei.
"You had the dream," said Nafai. "You knew it mattered. It made you want to tell Mother. We were here when you arrived, and she was not. But we, too, were brought together by the Oversoul. Don't you see that you have been invited?"
Shedemei shook her head. "My work is here, not on some insane journey whose destination is a thousand lightyears away."
"Your work?" said Hushidh. "What is the value of your work, compared to the task of restoring lost species
