So the author is a total wanker bigot that supports discrimination because of his narrow minded and cult-like 'religious' beliefs. But, unlike how this vile piece of trash the author is in real life, I am not going to let that influence my review of Ender's Game... 
 In the future, the human race was attacked by an alien race. The 'adults' in the future are idiots. I am surprised Humanity could withstand not just one but two attacks against the aliens who have never attempted to communicate with the natives. 
 Because of the current policies of keeping the people ignorant by cutting funds to public schools and higher education, it does not surprise me that Ender (age 6 at the start of the book) becomes the final hope of Humanity. Humans have lost their ability to think for themselves let alone 'think outside the box' for some reason and have resorted to recruiting young kids into Battle School. 
 While this book is classified as Science Fiction,I can actually see this happening not too far into our future. Only the extremely ignorant would think Earthers as the only space-faring species in the galaxy. Of course, when you get into the story, you realize there are exactly TWO space-faring species. Yes, much more believable then simply only humans traveling in space... 
 Honestly, I was told to read this book when it first came out in 1986. I waited all this time to finally pick up this book and while I did enjoy the story, just seeing all the subsequent books that has been published since Ender's Game, I am wondering if the Author is just trying to fill his bank account instead of telling a good story. If and when you read the follow-up books (Speaker for the Dead, Xenocide, Children of the Mind, Ender in Exile, and the myriad of books told from other character's perspective) I am thinking the follow-up stories is less about Ender.
