Ender's game

The author of the book that this post is named for is Orson Scott Card, whom I had heard of before but whose book I knew nothing. My mother gave me the book for my 30th as it was published in the same year I was born. If you had never read it you won't get what I mean but if you have:

I never thought I was emotionally invested by pg19 but when Valentine cried to Ender "Come back to me! I love you forever!" it just hit me...

So now in my 30's and once again.. ah.. same ol. What stock am I supposed to put in my age again?
