There were pools of light among the stacks, directly beneath the bulbs which Philip had switched on, but it was now with an unexpected fearfulness that he saw how the books stretched away into the darkness. They seemed to expand as soon as they reached the shadows, creating some dark world where there was no beginning and no end, no story, no meaning. And if you crossed the threshold into that world, you would be surrounded by words; you would crush them beneath your feet, you would knock against them with your head and arms, but if you tried to grasp them they would melt away. Philip did not dare turn his back upon these books. Not yet. It was almost, he thought, as if they had been speaking to each other while he slept.
