In a sterile city where citizens deliver black boxes containing stolen memories, Elias Thorne opens a forbidden box and finds a seed instead of a memory. He plants it, and a tree grows, cracking the white tiles of the Order. As the forest spreads, citizens begin to remember their lost pasts. Elias joins a network of gardeners who plant seeds across the city. The Order fights back with recalibrators and clones, but the forest cannot be stopped. Generations pass, universes are born and die, and the successful order continues—an eternal cycle of planting, growing, remembering, and loving.
