'Matt, Ben and Nicky have grown up together in the small town of Coolongawong in New South Wales. Last year a new girl came to town and Kris quickly became the fourth member of their group. Now the four friends are about to start Year 6 with the school's most popular teacher, Mr Mac. They discovered last year that by tripping on a creaky floorboard and saying the magic words History's a Mystery, they could be transported back in time and discover history as it is being made in exciting, and sometimes dangerous, adventures. They are now looking forward to another whole year of these adventures. In this second book they continue to meet some of history's most famous heroes and are present at some of history's most crucial times. Their adventures take them from visits back to the time of the dinosaurs and the Ice Age to the Ancient Olympics in Greece, the Vikings and Aztecs, to man's first time on top of Mt Everest and on the moon, from a rainforest adventure and a meeting with Ned Kelly to the last night on the Titanic and many more places in between.'
