Here's the publisher's description:
Pinmei's gentle, loving grandmother always has the most exciting tales for her granddaughter and the other villagers. However, the peace is shattered one night when soldiers of the Emperor arrive and kidnap the storyteller.
Everyone knows that the Emperor wants something called the Luminous Stone That Lights the Night. Determined to have her grandmother returned, Pinmei embarks on a journey to find the Luminous Stone alongside her friend Yishan, a mysterious boy who seems to have his own secrets to hide. Together, the two must face obstacles usually found only in legends to find the Luminous Stone and save Pinmei's grandmother--before it's too late.
A fast-paced adventure that is extraordinarily written and beautifully illustrated, When the Sea Turned to Silver is a masterpiece companion novel to Where the Mountain Meets the Moon and Starry River of the Sky.
I loved this book! This book is similar to its previous two companions in many ways. It features folktales from the story's universe interspersed with the rest of the book. These are interesting in that they're one of the few times when a book temporarily changes off-subject, and I don't think, Get back to the story already! They're as enjoyable as the rest of the story. The book also features many similarities to the past books, such as an abundance of characters, which have many different personalities. They change throughout the book, such as when Pinmei becomes progressively less shy. The language is very poetic and features interesting similes that you wouldn't normally think of. (I started to notice how struck I was by these.) This is one of those rare books that transports you!
