The Time-Traveling Vendor

Sylvia, from a poor ancient farming family, struggles. Her mother is bedridden with consumption; her father works far. She supports her brother by digging wild greens. In The Cave, the siblings trigger a two-way time portal, sending Sylvia to a modern marketplace. Discovering ancient wild greens are sought after, she travels between eras. She sells ancient goods in the present for money/medicine, bringing modern goods to the past, curing her mother and lifting her family out of poverty.
