Assault on the Mandrake Bastion

From the blurb:

Orius Adamantine, Lord-Celestant of the Hammers of Sigmar, leads a ferocious attack on the Tephra Crater to unseat the dread lord Anhur of the Bloodbound. In his path lies the Mandrake Bastion, a fortress saturated with dark magic. Succeed here and the Adamantine Warrior Chamber will have a vital foothold in the ongoing war against the Chaos forces seeking to open the Black Rift of Klaxus!

The Black Rift of Klaxus will be a serialized novel in eight parts, one part a month. Each part will be available as a digital download at blacklibrary.com, and–to the best of my knowledge–compiled in print format at some point and time in the future. But while you’re waiting, why not go check out an excerpt?
