Free Winter in Eden by Harry Harrison

ate cold food because she dared not risk a fire, fell asleep rolled in their furs.
    It was not easy, but she had never thought that it would be an easy thing to do. If the track had not taken the flattest route she would never have made it at all. Some days, when the path led uphill, no matter how hard she labored between the poles she still could only manage a small portion of a day's march that the sammad might have achieved. She did not let this bother her, nor did she let her fatigue come between her and what must be done. Each evening Harl gathered wood and they had a fire, warm cooked food. She would play with the baby and tell him stories that Harl listened to with close attention. The children were Winter in Eden - Harry Harrison
    not afraid of the darkness that began just beyond the light of the fire, that stretched out forever, and she would not permit herself any fear as well. The fire burned all night and she slept with the spear in her hand.
    There were many days of sunshine—then heavy summer rain. This went on for a long time until the muddy track became impassable for the travois. In the end she built a shelter of leafy branches and they crawled into it. She needed the rest, but despaired of the wasted time. Summer was too short as it was.
    Harl went out to hunt each day—and one evening returned with a rabbit. She skinned and cooked it at once and the fresh meat was delicious. The rain eventually stopped and the ground dried enough for them to start on again. But the next night, just before dawn, there was a frost that left the blades of grass tufted with white. Winter was drawing near again. With this realization there came the bitter knowledge that she would never make the long trek south along the shore before winter closed in. When she went to pack the travois she saw that she had been struck another unkindness. The death-stick was dead, the tiny mouth gaping open, killed by the frost. It was a creature of the south and could not live in the cold. It was a portent of the future.
    That night, long after the two boys were well asleep, she still lay awake in her furs staring up at the twinkling lights of the stars. The moon had set and the stars stretched above her in an immense bowl, the River of the Tharms running across it from horizon to horizon. Each star was the tharm of a dead-hunter, held up there in a glitter of cold light. Yet none of them could help her now. Had she been a fool to come on this helpless trek, to risk not only her own life but the lives of the two children? Perhaps, but it was too late to begin questioning. It was done. She was here. Now she had to decide what would come next. Had she any choice? Ortnar had told her she could wait on the shore for Kerrick, but he had been speaking stupidity, just to give himself an excuse for not going with her. She did not have enough supplies to last the winter on the shore, no tent, nothing to keep the winter at bay. So it was a choice then of camping and freezing—or starting south and freezing. There seemed little chance now that she could move south faster than the winter did. For the first time since she had left the encampment she felt tears in her eyes and was furious at herself for the weakness, wiped them away, rolled over and slept because she would need all of her strength for the next day's walking.
    The following night the first snow arrived and she shook it from the furs in the morning, packed them away and pressed on. That night, as they were eating, she found Harl looking at her across the fire.
    "Eat it," she said. "I like the murgu meat as little as you do, but it keeps us strong."
    "It is not the meat," he said, "but the snow. When do we get to the place you have told us about, where Kerrick is waiting?"
    "I wish I knew…" She reached over and brushed his fine blond hair, noticing the drawn lines about his eyes. He was eleven years old, a strong boy, but they had been walking steadily for far too long. "Sleep now, we want to
