I am reading When The Sea Turned to Silver. The main characters are Pinmea, Yishan, and Amah. They live in ancient China. Pinmea is a shy little girl, who lives with her grandma (Amah) at the top of a huge mountain. Amah tells stories for the travelers passing by. She also sells them beautiful silks. Yishan lives in a house not far from Pinmea and Amah’s. His father died, so he now lives by himself. He likes to come and hear Amah’s stories. At the bottom of the mountain, there is a village. It is ruled by a mean emperor. He is shipping people off to build the Great Wall. He will let the villagers stay if they give him luminous stone, but nobody has ever found any.
