Oxford in 2060 is a chaotic place, with scores of time-traveling
historians being sent into the past. Michael Davies is prepping to go to
Pearl Harbor. Merope Ward is coping with a bunch of bratty 1940 evacuees
and trying to talk her thesis adviser into letting her go to VE-Day.
Polly Churchill's next assignment will be as a shopgirl in the middle of
London's Blitz. But now the time-travel lab is suddenly canceling
assignments and switching around everyone's schedules. And when Michael,
Merope, and Polly finally get to World War II, things just get worse.
For there they face air raids, blackouts, and dive-bombing Stukas--to
say nothing of a growing feeling that not only their assignments but the
war and history itself are spiraling out of control. Because suddenly
the once-reliable mechanisms of time travel are showing significant
glitches, and our heroes are beginning to question their most firmly
held belief: that no historian can possibly change the past.
