Sorry I didn't see this before Tzism!
I myself practically grew up on 40K. I have an Eldar army gathering dust back in the UK, but I don't get a chance to play much any more.
Despite that I still
love the novels. Some of the writers for the Black Library are phenomonal. I have been
so impressed with the Horus Heresy books and eagerly look forward to each new one that comes out. Have you read them?
If anyone else is reading this and thinking of trying 40k books, start with the Horus Heresy. You will not regret it!
