All Clear: A Novel (Oxford Time Travel)

Winner of the Nebula Award

Traveling back in time, from Oxford circa 2060 into the thick of World War II, was a routine excursion for three British historians eager to study firsthand the heroism and horrors of the Dunkirk evacuation and the London Blitz. But getting marooned in war-torn 1940 England has turned Michael Davies, Merope Ward, and Polly Churchill from temporal tourists into besieged citizens struggling to survive Hitler€s devastating onslaught. And now there€s more to worry about than just getting back home: The impossibility of altering past events has always been a core belief of time-travel theory€"but it may be tragically wrong. When discrepancies in the historical record begin cropping up, it suggests that one or all of the future visitors have somehow changed the past€"and, ultimately, the outcome of the war. Meanwhile, in 2060 Oxford, the stranded historians€ supervisor, Mr. Dunworthy, frantically confronts the seemingly impossible task of rescuing his students€"three missing needles in the haystack of history. The thrilling time-tripping adventure that began with Blackout now hurtles to its stunning resolution in All Clear.
