Wow. This book really makes you think, which is usually something I dislike, but works here.
The style is really unique, and I enjoyed the way it progresses linearly, slowly revealing more and more with each report.
As mentioned in another person's review, it would have been nice to see a little more distinction between the character's narrations, especially when all of them apparently talk in language far more eloquent anything I could use naturally. However, doing this would diminish a lot from the overall feel of the story and would ruin the atmosphere and description, so I preferred to just think of it as the reporter heavily editing it to make it cohesive.
The ending was powerful too, and while I'd guessed lightly what could have happened, it was still a surprise, and wrapped up the story nicely.
