The World That Couldn't Be
“ It seemed incredible that an animal would become more formidable as the hunt progressed. But that seemed to be exactly what had happened. More spooked, perhaps, more frightened—only the Cytha did not act like a frightened beast. It was acting like an animal that was gaining savvy and determination, and that was somehow frightening.From far off to the west, toward the forest and the river, came the laughter and the howling of a pack of screamers. Duncan leaned his rifle against the boulder and got up to pile more wood on the fire. ”
