“Felix wasn't sure of his limits, if he had limits. After he'd been dead a while, he began to suspect he could swim to the bottom of the oceans. Beyond that. He suspected that he could swim so far down that he'd eventually go through the center of the earth and come out the other side. He could swim into the clouds, into the stars. Maybe there were ghosts on the other planets. Maybe there were ghosts laughing and splashing each other with the heat of the sun. He wasn't brave enough to find out.”
