In the very near future of 2009, two physicists working on a complicated experiment accidentally thrust the collective consciousness of the entire world ahead twenty-one years. Although the "flash forward," as it's later named, lasts only minutes, the aftermath is catastrophic. Not only are millions of people killed in accidents caused by their sudden and brief departure from the present (i.e. plane and car crashes, falls down stairs, etc.), but those who survived find themselves emotionally rocked by their respective (and sometimes shared) glimpses of the future. The two scientists are left to piece together what happened, while also trying to figure out whether or not the future they all saw was fixed or just one of many possible outcomes.
I enjoyed this book very much: the story itself was fascinating, and thought-provoking, and the author is clearly an intelligent man with an intriguing imagination. However, I had a big problem with the execution of the story; Mr. Sawyer's a great storyteller, to be sure, but an awkward, almost amateurish writer. While the book was an easy, accessible read, I found it to be equally as clunky and frustrating in parts -- especially his shockingly excessive use of the word "doubtless," which was so abundant that it became distracting and, toward the end, grated on my every nerve. (How his editors let it go to press with such a glaring flaw is beyond me.)
Still, I recommend this book to anyone who's interested in time travel and is looking for some light sci-fi reading. And, in spite of my feeling toward the author's technical skill as a writer (or lack thereof), the story itself was compelling enough to make me consider the idea of reading some of his other books.
