Sadly it is not every week we get something Horus Heresy related from Black Library. This teaser does sound very promising.
Our attention must turn again to Mars. It is held by the enemy, and poses a clear and present danger to Terra. There is only one solution.
Mars must be purged. The Red Planet must burn.
The war for Mars is coming
Now this is totally awesome and I sincerely hope it is another full Novel. I am just finishing of Nemesis on Audio then I will be getting through Deathfire.
Would be nice to think another Horus Heresy Novel is in the Barrel and Hopefully Dorn can get his blade wet.
