I loved this book. I found the story compelling and was impressed with how well it has fared in very different work technology wise since it was written. I was taken aback when I realized how long ago it was written but how well it translates to current technologies. Although the content could have been challenging (children "playing" war games) it was a thoroughly enjoyable read
