I also enjoyed it: one of my faves of 2011, and my personal favourite for the Hugo.
Letís start with the bad stuff because the good stuff is going to outweigh the bad. First, this is Part One of Two and we must wait until the fall of 2010 to discover what happens. This is my own particular pet peeve: if I know there is a must-have sequel, Iíll wait to buy the first book until the second is available.
Second, this book runs near 500 pages and a good 30% of that is travelogue. You could expect this from the opening citation. Itís from T.S. Eliot: History is now and England. Willis has a love affair in progress and wishes to share that love with her readers. The love affair is with England such that there are passages in the book that read like travelogues, particularly the one where we are given a guided tour of St. Paulís as it stood in 1940. The passage does nothing to advance plot or character. But, itís a very well done travelogue.
Next, we need to know that time travel, invented by Mr. Dunworthy and practiced at Oxford University, is performed only by a small group of historians. They go back in time to investigate particular aspects of some event. The rules governing this time travel mandate that no historian can go back to the same place more than once and no historian can do something that changes history. The universe will not let this latter circumstance happen. Either there will be no way to get the historian to the point of interest or nothing the historian can accomplish during the visit can have an impact on the flow of history.
Another rule is that the historian must arrive and depart unobserved by the folk of the time period to be visited. The locals are referred to as contemps. This law not only occupies the opening chapters of the book but defines the challenge facing the protagonists at taleís end.
Besides Mr. Dunworthy, there are four protagonists, all of whom are visiting England during 1940. Each assumes a cover name while traveling. If Willis explained why, I missed it. The time travel technicians are always busy but, as the story opens, seem to be busier than usual causing all manner of schedule changes for the historians. Schedule changes impact dress, speech, and the research necessary for the trip though much of the detail they need can be furnished via implants.
The affected historians in this tale are:
Polly Churchill/Polly Sebastian/Lieutenant Kent: interested in life in London during the blitz, particularly Londoner behavior in the air raid shelters as well as service as a First Aid Nursing Yeoman, FANY, in 1944 Surrey,
Merope/Eileen: interested in the life of the children evacuated to the countryside, in this case Warwickshire.
Michael Davies/Mike Davis: interested in unsung heroes. He had planned to be at Pearl Harbor but a schedule change sends him ostensibly to Dover to watch the evacuation from Dunkirk.
Gerald Phipps/Ernest: interested in military intelligence as in posting mock tanks about the countryside to mislead German reconnaissance planes.
And then there is Colin, a 17-year old wannabe historian who has made one previous jaunt into time. He is earnestly in love with Polly, 7 years his senior. While waiting to attend Oxford and become a full-fledged historian, he spends his time researching material for Polly.
Another feature of time travel is known as slippage. Historians are sent to a specific date and time but slippage can cause the arrival time to be earlier or later, sometimes much later. Each of the four historians experiences some slippage but Mike experiences the greatest amount arriving a good deal further from Dover than he anticipated and two days later. This places him in Saltram-on-Sea and ends up with his participation in the evacuation of Dunkirk, a circumstance not supposed to be possible. He accomplishes a thing or two at Dunkirk that he comes to believe he shouldnít have. He is also injured which puts him out of action for several weeks. When Mike clears his coma, he is terrified of what he may have done to history.
Polly arrives later than expected to London at a time when the air raids have already begun. She carries an implant identifying every raid and its outcome through October 1940
Eileen experiences a measles epidemic that runs through the evacuee population causing their residence to be quarantined. This keeps Eileen from visiting her drop site at the appointed hour. By the time she gets there, it isnít working.
Three of the four historiansí drop points become unavailable either due to circumstances, such as an anti-aircraft gun placement, or simply cease functioning for reasons unknown.
These three, due to non-functioning drop sites, gather in London at the point where Pollyís knowledge of raids and outcomes is about to expire. Knowing their own drop sites to be out of order; they hope that their fourth colleagueís site remains functional. The little problem with the fourth colleagueís drop is that they are not certain exactly where in England he was supposed to go nor what cover name he is using.
Although Mike remains terrified he has done something to change history; Polly suspects he hasnít because she knows she has visited V-E day. She is reluctant to tell him as the problem with the drops may indicate what she think she knows is no longer true.
The final chapter describes the arrival of another time traveler. Whilst this man remains unidentified, the odds are pretty good that itís Colin come to rescue Polly.
So, what do we get in this tale? We get a rich look at 1940s England, in the city and the countryside. We get an up close and personal view of Dunkirk. We get a good review of medical facilities and practices in the 1940s, e.g., how does one break the fever associated with measles without antibiotics? We get a marvelous description of life in the tubes and shelters during air raids and the behavior and character of the Londoner. We are also introduced to four singular time travelers with all their accomplishments and failings. Sometimes, we think that folk from 2060 ought to be more aware of the world around them and how to deal with it but, then, we ourselves are forgetting they are operating in a world of 120 years ago. 120 years ago today, weíd be hard pressed to recognize all the ins and outs of 1890s daily life.
And, we get a neat mystery as to what is happening with the time travel apparatus, the problem identified by the storyís title. Unfortunately, we must wait till Part Two to discover its resolution.
This is a great story and a recommended read though you may want to wait till Part Two is available.
