“ He still heard his mother's voice--Davey--rise like whisper-dust from unseen corners in the house, but it was no longer the only voice he heard. His ears were also filled with the voices of others--his father and Primrose and Refrigerator John and his grandmother. Of course, all of their words for a thousand years could not fill the hole left by his mother, but they could raise a loving fence around it so he didn't keep falling in. ”
