I love when you get a great setup, like this one, and then the author throws a twist in the first third of the story. It's great to get to see how the twist plays out, rather than having the twist at the very end where it just leaves you hanging. This was a very enjoyable and compelling read. The ending, however, was a little too tidy, a little too handy, a little too "and now we'll all have world peace." Still, I enjoyed it.
