This was a book that I read first a long time ago and decided to pick up again for the Kindle after it came back at the top of some Goodreads recommendations.  I have to say that whereas a lot of books from my childhood lose their intensity and color as I have grown to expect more from what I consume, this one holds up very well.  The character of Ender, while very young through much of the book, thinks as an adult and is therefore easily relatable.  Not that I could compare to the character of Ender, but having been though many advanced classes and having been tested to failure on more than one occasion, I sympathized with his feelings of emotional separation and ones analytical objectivity as a contributing factor to that isolation.  I would say that this is a “must read” for anyone the least bit interested in Science Fiction and unlike before, when I stopped after this book, I plan on reading my way through the entire collection of stories in Enders universe.  The twist ending is significant and plays so well into the emotional underpinnings developed for the second book that even though this book is so starkly different than Speaker for the Dead, that they fit almost perfectly together.  One suggestion I have would be to make sure that you get the novelized edition that was written later on so that you have a better segue into the second book and although I usually skip these, the forwards by Card are very interesting.
