It was supposed to be a relaxing mini-break when the whole Hathaway family go glamping. Instead in usual Gemma and Edward style they are drawn into yet another adventure.
In the beautiful Able Tasman national park everything is not serene and soon Edward has fallen through a waterfall and through time. In her attempt to find her brother Gemma investigates the waterfall only to fall through the time portal herself, with Will following close behind.
But they are all at separate locations and face the adventure alone. An adventure that is sometimes a little more nightmarish than they would have liked.
And then there is Kingi, a local Golden Bay boy who adds more mystery to the plot. When Prue meets Kingi she too wants in on the scheme to locate local treasure and now all safely back through the waterfall they go searching.
More time travel for Will and Edward sees them wandering 18th century English countryside and Prue and Gemma face a loaded gun.
Time travel, treasure maps, legends, faeries and sinister men all add a mix of dimensions to the story. The children have more riddles and puzzles to solve and strange creatures to face. Which they do with the help of Will a drone robot with futuristic abilities.
