The Legion of the Damned Codex is out:
From The Black Library:
Appearing from the shifting tides of the Warp, the Legion of the Damned are mysterious bone-adorned Space Marines who arrive unlooked for to aid the servants of the Imperium. No one knows for sure where they come from, but none can doubt the fury with which they fight, or the trail of dead foes they leave in their wake. Tormented by a ghostly past and afflicted by the very power that snatches them from one battlefield to the next, the Legion are truly cursed warriors who, perhaps, seek salvation through the carnage they visit upon the enemies of the Emperor.
