This inevitable release to tie in with the new tv series is sure to have people rushing to read it in the hope of finding answers to the numerous conundrums and Lost-style red herrings that have already been provided. So a word of caution: this book was written ten years ago and the series is only based on the book's central idea. There are already massive changes of direction and focus from the book, and it's likely the direction may go further apart, especially if the series runs for a while. That's not a bad thing though as the central idea is one of Sawyer's best and can be explored in many ways.
What would you do if you knew what the future had in store for you? This is the intriguing question that some scientific technobabble involving quantum mechanics throws up. Free will versus apparent predestination is a fascinating concept. The predicament of the characters, some of whom learn how they'll die and when, and some of whom learn how their lives will turn out for better or worse, is an idea that grabs the attention. Some people give up and accept the inevitable, some people just give up and kill themselves, some people try to change the future, and some people even try to ensure the future they saw does happen.
These attitudes build up a picture of the various views of fate we probably all have and as such it represents the very best that science fiction can provide. Sf always works best when it takes a single idea and asks how the world will change because of it. What I found less successful was the science aspects. I've enjoyed a few Sawyer novels and for me they usually get bogged down with trying too hard to make the science believable, when it rarely is. Sawyer's writing style is also prone to being pedestrian, but on the other hand it's well within the norm for the modern bestseller style.
Some minor reservations aside, this is a fascinating novel of ideas and how we might react to knowing our fates. Whether or not the tv series takes the same direction, both are well worth exploring.
