What can children teach the world? Christie Hsiao's latest book, Journey to Rainbow Island, is giving the question a go.

To be released in early November, the novel follows 11-year-old Yuning on a journey to secure sacred stones that have been stolen from her home island. Through the book, Yuning has to "overcome not only the darkness attacking her home, but also the scars of sadness that mark her own heart", according to a synopsis.

Hsiao, who was born in Taiwan, says she's the perfect person to write a children's book because she still sees herself as a child sometimes.
