A fairytale castle stands high on a plateau in Australia’s Blue Mountains. Inhabited by a strange boy and a grumpy old man, it is just too much for orphaned twins Jolie and Joey to resist.
Defying warnings from the townsfolk of Wattle Gum, the twins venture across the castle’s threshold and quickly unravel its mysteries.
But sinister forces soon separate the twins, and they must battle powerful enemies from all corners of the universe to reunite and save the world.
It is a story about belonging, about outsiders seeking a place of their own.
