'In most ways Tommy Marsden is your average eleven year old boy; he annoys his older sister Annabelle, and enjoys hanging out with friends. What sets Tommy apart from other kids his age is his interest in shortwave radio, and the fact that he is busy building a time-machine in his bedroom. When he goes missing in strange circumstances on the same day as the Centenary Celebrations are to be held in Upper Wattle, Victoria, Annabelle wonders if he could be the 'boy who fell out of the sky' 100 years ago. Tommy's grandpa, Tom Marsden Senior, has another theory; and so the search for Time Warp Tommy begins. Spanning the globe in an adventure worthy of Biggles, Jim Sinclair captures the mystery and drama awaiting Tommy Marsden. Kidnapped by a man with many names and shipped to the isolated rogue nation of Yaroon for the sole purpose of encouraging his research into Time Travel, how will Tommy survive? As other young people join him, he realises there is something amiss. Were his parents really killed in a car accident? What ever happened to his sister & grandparents? Will he ever be able to escape and find his way home to Australia to reunite with his family?' (Publication summary)
