Joshua's father bought graph paper at Walmart. Unfurled and penned on the wall where his mother's family pictures had once hung, it stood six feet high by seven feet wide. The paper was hung in three rows, each printed with thousands of small gray squares. If Joshua crossed his eyes, the squares seemed to rise from the page. It's time we started a map, his father had said, or we'll never finish this game.
