Any advice as to where someone completely new to the 40k universe should start?
I've picked up "15 Hours", and another novel dealing with the crew of a Leman Russ battletank (I think it was called Gunheads), but I'm having trouble finding anything dealing with the more RT-related things, i.e. the operation of starships, what sort of people the high and mighty are, etc. Does anyone have suggestions of a few titles that show off the Rogue Trader setting a little more? Even an idea of which rulebooks for different 40k games contain heaps of background fluff would be helpful. I work in a bookstore, so usually price and print availability aren't huge issues.
