JUST BEFORE AWAKENING , she had dreamed of the flight from Eritrea, the six-month barefoot march into the Sudan and the quest for a refugee camp willing to take her group. The faces had faded from her memory, but the landscape, the vegetation, the feel of the march had stayed with her and become the continuo line underlying many of her dreams. Usually it was northern Eritrea, which they had marched through during the first days of the journey, when her mind had been fully open to the new sights and impressions that, once they hiked free of the caves in which she had spent her earliest years, seemed to present themselves to her every moment. The terrain was endless brown hills separated by the arroyos of seasonal streams and barely misted with scrubby vegetation. Nothing like the terrain she was running through now, densely grown with huge cedars and carpeted with ferns. But she knew that if she gained enough altitude, she would find herself in territory like what she and Chet had traveled through yesterday: steep, wide-open country where you could see for miles. And going there was not optional. If she stayed to the low moist valley of the river that flowed south from American Falls, it would lead her off in the wrong direction, taking her down into the basin of a major lake system that drained southward. It might be two days’ hiking down into those lakes before she could reach a place where she could summon help. To reach Uncle Jake’s, she would have to climb out of the valley and above the tree line to the lower reaches of Abandon Mountain, which she would have to traverse for several miles until she came to the headwaters of Prohibition Crick. That bit, she already knew, was going to be the desperate part: that was where she’d have to summon whatever it was the leaders of her refugee group had summoned on the worst days of their trek, when they were tired, short on food and water, and being pursued by men with guns.
