" With all the planning she’d done, she must have known she was leaving, and even she couldn’t have been totally immune to the feeling. She’d had good days here. And on the last day, the bad days become so difficult to recall, because one way or another, she made a life here, just as I had. The town was paper, but the memories were not. All the things I’d done here, all the love and pity and compassion and violence and spite, kept welling up inside me. These whitewashed cinder-block walls. My white walls. Margo’s white walls. We’d been captive in them for so long, stuck in their belly like Jonah. "
