As revealed in cod extracts from a later guide book quoted at the beginning of each section of this novella the Jewelled Valley was once ruled by a royal family of “Jewels” who could bind the powers of precious stones to influence minds and so tamed the gems. Each Jewel had a similarly bound servant, a Lapidary, who could hear and speak the stones.
The action of the book is set in the end-time of the Jewelled Court. Lin is the youngest daughter of the King, her Lapidary, Sima, the daughter of the King’s servant. Driven mad by the gems, Sima’s father has betrayed the Court and destroyed most of the jewels. Lin is the only member of the royal family to survive, the only person who can protect the people of the valley from the invading army of the Western Mountains. Sima sticks to her vows not to betray her Jewel.
Wilde’s control of her material is accomplished enough but it doesn’t stand up to a moment’s scrutiny. Gemstones with mind-controlling powers? That can be muted by being placed in a setting? But it is a fantasy. And short enough to read in one sitting.
Pedant’s corner:- if a Lapidary broke their vows (several instances. Lapidary is singular; so “his or her vows”.)
