there's no doubt a wind, too."
Ivan despaired. "Why do you have to argue with me? You're not stupid. This is my world, not yours, and if I tell you that magic is different from tools and the difference matters, then you should spend your time trying to understand the difference, not arguing with me."
She seemed about to answer with another argument, but then stopped herself. "The difference really is important?"
"Yes."
"Then explain it to me, and I'll try to understand."
The result was a painful hour of explaining electricity and wires and circuits, along with a vague explanation of cameras. And by the end, Ivan wasn't altogether sure that she understood anything. Except the one most important thing: That she not use magic in this world, not in front of other people, nor even speak of it.
"They don't believe in it?" she said. "Even though it works?"
"It takes talent and training to use magic," said Cousin Marek, who had listened to Ivan's explanations without helping once. "While any fool can use a machine."
"Any fool who can afford to buy one," said Ivan.
"And any fool who can afford to hire a wizard has magical power at his command, too," said Cousin Marek. "And now who's arguing for the sake of argument?"
The next day, the tickets arrived for Katerina's flight, and Ivan changed his reservations so they could sit together. "You can conjure money out of thin air?" Ivan asked Cousin Marek.
"Of course not," he answered.
"Then what magic did you use to buy her ticket?"
"American Express," said Marek.
"An immortal carries American Express?"
"Not my American Express," said Marek. "What use would I have for such a thing? When I want to travel, I walk. No, the card belongs to a friend. Your family are not the only folk to leave this land and go across the sea. And not all who leave this place forget their Cousin Marek."
For the first time, Ivan realized that this might have happened before. "Did you help us get our visas to leave the Soviet Union, back when Mother and Father and I lived here with you?"
"I tried."
"Then why did it take all those months?"
"I didn't have such good connections in Moscow," said Marek. "And I wasn't all that eager for you to leave."
With passport and ticket, and a decent selection of clothes that more or less fit her, Katerina was ready to go. Ivan was not, for when he returned to America he would have to face Ruthie and Father and Mother and somehow explain Katerina to them all. But there were no more reasons for delay, and many reasons to move quickly, not least of which was that Baba Yaga was still hovering nearby, plotting who-knew-what nastiness.
They bade good-bye to Sophia and rode with Cousin Marek to the train station. Ivan noticed that Katerina showed no fear of climbing inside Marek's truck. Perhaps that was because her trust in Mikola Mozhaiski overrode any fear. Or perhaps she had believed him when he told her it was simply a tool. Though, given the number of people who died each year in auto accidents, it might have been wiser for Ivan to warn her not to get into any kind of car.
When they got to the train station, Katerina immediately grasped the idea of many cars being pulled along a track by a single engine. "The locomotive is the ox," she said, "and it pulls these houses like sledges across snow." Close enough, thought Ivan.
Cousin Marek walked the length of the train. Only when he was assured that Baba Yaga wasn't aboard did he let Ivan and Katerina get on. "Be alert," he said to them both. "Watch for her, and don't let her talk to you. She can persuade the sun it's a pudding."
"She can't outrun a train, can she?" said Ivan. "Or outfly a jet? So we're safe."
Marek scowled at him. "Don't wear the hide until the bear is dead," he said.
"How will we know her if we see her?" said Katerina. "We might have seen her yesterday, but she can seem to be whatever she pleases."
"Look at her eyes," said Marek, "and you'll know. She can't change those, not without being blind."
"Look at the eyes and see what?" asked Ivan.
"The enemy."
Ivan had long since learned that when Cousin Marek didn't want to give a straight answer, he went in circles, and they were circling now. Rather the way Ivan had led the bear around the chasm till it gave up.
As the train pulled out of the station,
