Just when you thought it was safe to go back in the past!

It's News Day again for Sascha Martin, Landfill Public School's inventive 8 year old, and a new invention brings his classmates face to face with the living, breathing, stomping, chomping, leaping, climbing, gnashing, slashing megafauna (really big animals) that lived in Australia 12,000 years ago. Plus a ring-in from much, much earlier, and he's not happy at all!

Life back then was all about not being eaten, and the challenge is almost too much for Sascha, Luca, and Mary-Alice, and Mr Jack and Mrs Barnum, and all the other teachers and children swept up in Sascha's new Show and Tell miscalculation.

This hilarious, epic sequel to Sascha Martin's Rocket-Ship adds a new twist to the time travel genre, poking the boundaries of science fiction and taking children where no child has gone before - to a school overrun by enormous prehistoric creatures.
