Wonderful collection of all four Ender's Shadow series books. Though I personally expected that I would prefer the Ender's Series to its Shadow Series counterpart, these books took a hold of me and didn't let me go until the very last page. Mr Card details a wonderfully complex and ever changing, yet easy to follow narrative. Having personally read hundreds of books, I have never recommended a series more strongly that I have the Ender's Game series. I have yet to read Ender in Exile, but plan on picking that up quite soon. Deep, political, emotional, philosophical, psychological, and religious questions are brought up here. Though Card is more conservative than I am, he offers a balanced perspective in his works. Most impressive, I felt, was how he turns thoughts into action, showing the growth of his characters and ensuring that you never feel like you're reading through the filler to get to the next good part.
Highly recommended for any reader, but particularly for those who want to make reading a more solid part of their life and haven't yet found that right book to do so with. This series did that for quite a few people I know, and I'm sure it could do it for you as well.
