The young man was very quiet, obviously recalling something important.
He had spent the entire month of July in hospital, at his mother's bedside. Her long fingers had felt like bones bundled in thin silk, and they offered no resistance when he squeezed them. When at last he felt some slight pressure, almost indiscernible, he watched her face. She opened her eyes and met his gaze for just a moment before the muscles of her face contracted, as if in pain. Her eyes clamped shut in a last grimace, and each inhalation came several seconds after the last. Joe watched a vein below her ear pulse like the heart of a frightened bird.

He watched until it went still and all the lines on her face smoothed away, and then he laid her hand, still loose in his, atop the crisp, white sheet.
