I finally had a chance to read the 4th and last book in the Ender Quartet, Children of the Mind, by Orson Scott Card. I think this one is my third favorite in the series (my least favorite being Xenocide). I am pretty happy with the way things ended up - happily ever after for the most part. I don't really have that much to say about this, it was a good read. It pretty much just tied up all of the open story lines pretty nicely, which is kind of annoying, but I am satisfied.
