"A new classic fantasy adventure." - Eoin Colfer, author of the internationally best-selling Artemis Fowl series

An outsider in her village above the cloud sea, 12-year-old orphan Yeung Zhi Ging's only hope of escape is to win the single invitation to train as a Silhouette: an apprentice to the immortals. After her ill-fated attempt to impress the Silhouette scout leads to a dragon attack on the jade mountain, Zhi Ging is sure that her chances, and her life, are over. But the scout spots her potential and offers her protection and a second chance. She's in.

In her lessons in Hok Woh, the underwater realm of the immortals, Zhi Ging must face the challenging trials set by her teachers to prove that she's worthy of being a Silhouette-despite her rivals' attempts to sabotage her. But as Zhi Ging's power grows, so do the rumours of the return of the Fui Gwai, an evil spirit that turns people into grey-eyed thralls.

When the impossible happens and the Fui Gwai attack the Silhouettes, can Zhi Ging use her newly uncovered talents to save her friends and the world beyond? Or will the grey-eyed spirit consume them all?
