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.

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.
