Dinosaurs, Opals and mysteries in the Australian Outback

Josh and his father, Steve, go to Lightning Ridge, an outback opal mining town in Australia, in the hope of making a fortune mining opals. All does not go to plan when there is a catastrophic event in the mine they enter. Steve, searching for help for Josh, comes across a team who are working to retrieve extremely rare and precious opalised dinosaur bones. Lightning Ridge is the only place in the world where these precious artefacts are found.

They are not the only people who would like to recover such a valuable fossil, and in the dead of night Josh unwittingly becomes involved in a robbery attempt.

Will they foil the robbers? Will the opalised bone be safe?
