The ice crossing remained a twisted combination of seductive ease and sharp discomfort. After he left the outpost behind, Sparr enjoyed two days of easy travel. The skies were clear, winds calm, and navigation simple. Once, crossing a bay, he spotted a sailing ship struggling through the chop. While he flew high above, the ship pitched and tossed in the cruel sea, its crew and passengers no doubt unable even to sleep. Any worry that he had chosen the wrong path was wiped away as he imagined their misery. Other times, however, it was all he could do to survive the night. Wind howled across the tundra, unchecked by forest or protective ridges. Those nights he and Bogg would huddle miserably on the floor of the air car, shivering and alert, while wild creatures yipped or howled about them.
