Anything Cadia is on my list to discover since it was taken. I have a lot of Cadian miniatures.
Here is the latest novel from the Black Library that you can get a hold of early!
Also you can still get a hold of the Advent Calendar stories.. they are still available until the end of the year. You can do that here as well as get the Scourge of Fate.
