Ender's Game

What interested me and made me want to pick up this book:
I feel a little guilty saying it since I like to consider myself well-read, but I had never even heard of this book before the movie came out.  I haven't seen the movie yet and won't until at least when I'm done reading the book, but lots of my friends saw it, and I kept hearing so many good things about it.  It became as well known and as much talked about as "Frozen" has more recently.
Once I heard the basic plot of the movie, I couldn't wait to get my hands on the book, mainly because I'm just a nerd like that and if given a choice between a movie and a book I will almost inevitably choose the book.  I'm really just not into movies.
Science Fiction has always been my favorite genre to read and write, and I thought the concept of the story's plot was so exciting.  It intrigued me that in the beginning of the story Ender is only six years old- just a little kid, and the idea of six year olds training for battle is such an anomaly in our time that it hooked me in and held me there.
Another thing I feel guilty about is saying how much the cover drew me in.  But I don't think it's necessarily a bad thing to get drawn in by the cover of a book, especially if there are so many other good things about it.
This, of course, is a movie poster and not a book cover, but the picture of the boy in a flash suit (what they where to train for battle) is the same, and so is the font and color of the text.  This is easily one of the coolest covers I have ever seen on a book.
