A “golden age” that growls with hunger.Lin has no grand plan—only a wish:let the little bean who waits for her at the gate eat his fill,let the gray-haired elders who calls her “treasure” sleep without fear of famine.Lin Wanwan wants to bring small changes to the world she loves, so the family she cherishes can live a little better, then a little better still—because“I has finally found the place that calls my home.”
