Rae Banks returns to her hometown to take over a vegetable plot, discovering it connects to ancient times — one modern hour equals one ancient year. Facing villagers with no harvest during drought, she brings seeds, technology, supplies to help them, receiving old items in return. She builds a successful business, leading villagers to shared prosperity; she also shows ancient women they can pursue education, careers, and live on their own terms. This garden connects two eras, growing happiness.
