Ancient and wise, the grandfather Koi knows at first sight that this human bears a hidden wound. But how can a mere fish, even one as old as himself, be of any aid to a human? Astronaut Tyler Lanham had come to Grissom City, first and oldest lunar settlement, in search of the medical expertise he couldn't find on the far side of the Moon. When he sees the scar on the ancient koi's side, he knows he's found a kindred spirit. But an enemy is stalking these lovely gardens. A danger that will change both man and fish. A short story of the Grissom timeline.
