Matt, Ben and Nicky have grown up together in the small town of Coolongawong and are now in Year 5 with the school’s most popular teacher, Mr Mac. A new girl joins their class. Kris is determined to hate her new school. However, with her three new friends, she discovers that they can go on the most amazing adventures within their classroom. They find that by tripping on a creaky floorboard and saying some magic words, they can be transported back in time and discover history as it is being made in exciting, and sometimes dangerous, adventures. Together they meet some of history’s most famous heroes, and are present at some of history’s most crucial times. Their adventures take them from Ancient Egypt to Pompeii, from Antarctica to Japan and from Camelot Castle to the Eureka Stockade, with many more places in between. Dell Brand grew up in Sydney and taught in state high schools during her working life. Trained in PDHPE, she was recognised with the Minister's Award for Excellence in Teaching and the Outstanding Achievement in Education Award from the Australian College of Education for the development of alternate courses for senior students who wished to stay on at school and complete Years 11 and 12 but had no desire to pursue further study. She has three degrees in Education and her Ph.D. reflects her keen interest in working with children with challenging behaviours. For a number of years Dell worked in a wilderness-enhanced program aimed at turning around young people's lives. As a teacher in this program, she involved herself in many of her recreational passions including abseiling, rock-climbing, wilderness trekking, canyoning and canoeing. More recently she developed a particular interest in family history and history in general. Whilst still teaching, Dell completed a course in journalism and became a part-time freelance journalist. She was published by a number of editors in Australia and abroad. She wrote her first children's book, History's a Mystery, in 2010 in an effort to teach about some of the great events in world history to upper primary aged children. Due to its success, three more books followed. Using her own travel experiences to write first-hand about places she had seen, many found their way into these books.
