A Rebel in Time
Colonel McCulloch is head of security at a top secret research station near Washington. He is also taking a great interest in the period of the American Civil War, and has stockpiled a quarter of a million dollars in gold.
Agent Troy Harmon is assigned to investigate McCulloch's behaviour when McCulloch becomes a suspect in two murder cases. But McCulloch has completely disappeared. Harmon discovers that the research station was conducting experiments in time travel, and he realises that McCulloch plans to travel back to the time of the Civil War and alter history.
Harmon must follow McCulloch back – it will mean a one-way trip, and great risk for a black soldier in this period of time.
Harry Harrison
Harry Harrison (born Henry Maxwell Dempsey, 1925–2012) was an American science fiction (SF) author, best known for his character the Stainless Steel Rat and for his novel Make Room! Make Room! (1966). The latter was the rough basis for the motion picture Soylent Green (1973). Harrison was (with Brian Aldiss) the co-president of the Birmingham Science Fiction Group.
Aldiss called him "a constant peer and great family friend". His friend Michael Carroll said, "Imagine Pirates of the Caribbean or Raiders of the Lost Ark, and picture them as science-fiction novels. They're rip-roaring adventures, but they're stories with a lot of heart."
