This seems new, list of HH Books, Audio dramas and short stories in a rough chronological order!
The afterword of Unremembered Empire mentions all the books it ties in together, i think its a really important part of the series as it sets the stage for the next part of the Heresy, a pivotal moment in the history, you get to know where a lot of people are and what they're going to do, its like Isstvan, the next big marker for the series.
