The most wonderful Deltora book of them all. It is beautifully illustrated by Marc McBride and the writing by Emily Rodda is equally stunning as all her writings are.
There are two parts to this book. The first part explains the ancient history of the Shadowlands, the Ak-Baba and the Shadowlord. The second is about how Adin, the first king of Deltora and also the maker of the Belt of Deltora, united the seven tribes (Del, Ralad, Plains, Mere, Dread Gnome, Toran and Jalis) and collected each of their gems (the topaz, the ruby, the opal, the lapis lazuli, the emerald, the amethyst and the diamond).
