So with this edition of 40k, there's been a very deliberate attempt to shift the setting forward a little, keeping most things the same but shifting them on in time just a little bit.

My question is, outside of the main army books, what Black Library books have advanced the setting so far? I can think most prominently of one of Gav Thorpe's eldar novels that deal with the Eldar, post the events of Eye of the Storm, but what else? And do they do it in ways that are satisfying?
