The siblings Marcel and Julia accompany their father, a successful animal photographer, to the Australian island of Tasmania to take photos of the Tasmanian devil. When their father disappears suddenly and without a trace and they set out to look for him, they fall into a shaft. First, it looks like a burrow of a wombat, but then it turns out to be a previously undiscovered, huge cave system – in danger of collapsing, inhabited by dangerous animals, and full of wrong turns! Will the twins be able to escape this hellish labyrinth? The third volume of the action and adventure series by Andreas Schlüter. With illustrated nonfiction pages and including survival tips.
