As I read this I am listening to an Audio version of my favourite book. This is of course Endersgame. I love a lot of OSC's work, although I find some of his work like speaker for the dead and the worthing saga, more fantasy than Sci-Fi.
He is a brilliant author, and I always look forward to his next book. (just finished reading Ender in Exile)
Thanks for the link, it is very interesting
