The good news is that "All Clear" is an improvement on "Blackout", the first part of this novel that turned out so long that it only seems to go by the name of its two parts, "Blackout/All Clear". "Tinhead" and "J. Irish" have summed up its strengths and weakness perfectly in their reviews: in "Blackout" the time-travelling protagonists investigating different aspects of World War Two were all involved in their separate activities, and we had a soap opera with masses of very dull detail and next to no dramatic tension. In "All Clear" the time-travellers find each other in London and begin to seek a way out of their predicament, which is that they are stuck in the middle of the Blitz because their time gates won't open. This brings some genuine dramatic tension to the book, and you begin to care a bit about the characters. The time complications start to become more interesting, and Connie Willis's enormous amount of research begins to pay dividends. And in the end she makes a pretty good job (in so far as anyone can!) of resolving the time paradoxes. And yet! ... the book remains infuriating: like "Blackout", it is still far too long, too soapy, and too full of dull minutiae. If only the book had been 300 or 400 pages long rather than well over 1,000, we could have had a terrific time travel novel fully deserving of the Hugo and Nebula Awards it has won, instead of simply rewarding Connie Willis's undoubted effort and her status in the American science fiction community.
