Alex followed the pair of them across camp, stepping cautiously on the treacherous earth. His occasional curious glances up from his endangered feet across camp didn’t much impress him. There was a monkish air about the place, a kind of military desiccation. Four skeletal towers dominated the camp, with microwave dishes, racks of spiny aerials, wrist-thick wiring and cable guides, and whirling cup-shaped wind gauges. Three large, dirty buses were parked side by side under a flat paper sunshade, along with three robot bikes. A tractor with a dozer blade and a spiraled posthole digger had planted a set of tall water-distillation stacks, which were dripping into a fauceted plastic reservoir.
