" His unfinished book had become his obsession. He rarely left his room, which he insulated with sheaves of paper scribbled with beginnings and endings, nailing ideas to the walls and stretching long strips of sentences from the window to the door. Tall stacks of scenes and chapters sprouted from the floor, as if the papers had reincarnated themselves back into trees. The paper forest around him glimmered in the sun from the windows, weaving rays of light in yellow and purple and blue. Hunger squeezed his throat, but he turned his ravenousness toward writing. He almost never slept. During the shortages, he wrote between the columns of old newspapers, or on pieces of cardboard, or on bark pulled from trees. He traded potatoes for ink. "
