Boon led Mira to a dusty supply closet and pulled out a logbook. "Eda left this for whoever came next," he said. The last page held a hand-drawn map of the station, with one room circled deep in the lower level. "She said go here when the plants turn. I never had the nerve. You might."

Mira begged Boon to come with her. He shook his head, then stopped. "No," he said slowly. "I let your grandmother go alone. Not again." He grabbed a lantern and stood up straight for the first time in years. Together they walked down into the dark, following the plants, and this time the old engineer was not afraid.
