Well, I must say that this book is infinitely better than Xenocide. Fresh ideas, fresh character development and less of a scientific approach. It was well worth plugging through Xenocide to get to it.
Still didn't have the pinash that the first two books did. Speaker of the Dead was an amazing concept and Ender's Game had such a nice way of framing the struggles of a boy who was learning who he was in the world and what he was capable of. Children of the Mind focused more on ammending one's view, even if it turns out to be the only thing you felt comfortable that you knew as the truth. You could tell that there was no one master point, like in the first two novels, but it was a much more enjoyable read than the tech-speak of it's predecessor.
Now, on to Ender's Shadow. Will let you know how it turns out.
