All Clear

In Blackout, award-winning author Connie Willis returned to the time-traveling future of 2060, the setting for several of her most celebrated works, and sent three Oxford historians to World War II England: Michael Davies, intent on observing heroism during the Miracle of Dunkirk; Merope Ward, studying children evacuated from London; and Polly Churchill, posing as a shopgirl in the middle of the Blitz. But when the three become unexpectedly trapped in 1940, they struggle not only to find their way home but to survive as Hitler's bombers attempt to pummel London into submission.

Now the situation has grown even more dire. Small discrepancies in the historical record seem to indicate that one or all of them have somehow affected the past, changing the outcome of the war. The belief that the past can be observed but never altered has always been a core belief of time-travel theory, but suddenly it seems that the theory is horribly, tragically wrong.

Meanwhile, in 2060 Oxford, the historians' supervisor, Mr. Dunworthy, and 17-year-old Colin Templer, who nurses a powerful crush on Polly, are engaged in a frantic and seemingly impossible struggle of their own - to find three missing needles in the haystack of history.

Told with compassion, humor, and an artistry both uplifting and devastating, All Clear is more than just the triumphant culmination of the adventure that began with Blackout. It's Connie Willis' most humane, heartfelt novel yet - a clear-eyed celebration of faith, love, and the quiet, ordinary acts of heroism and sacrifice too often overlooked by history.
