If you could travel into the past and prevent the death of your father, would you? Thirteen-year-old Noel Villan must make this decision in a story of bereavement, time travel and nuclear war. Noel has discovered a bunker within the forest near his hometown. What appears at first to be an air-raid shelter is found to be a forgotten Cold-War era time machine, capable of sending humans into the past to prevent the end of the world after a nuclear war. Noel plans to use the machine to change the past and prevent the accident that took his father’s life. Along the way, he learns about an enigmatic character, Owen Milburn, who mysteriously disappeared without a trace in 1989 and his involvement in the nuclear deterrent programme. Who exactly is Owen Milburn? What are those huge golf ball structures that dominate the landscape outside of his hometown? What is the Ministry of Defence? And can he, or more importantly, should he prevent his father’s death?
