My new Horus Heresy short story

Dark Heart, the Horus Heresy story that I wrote for the forthcoming anthology Mark of Calth is now available to download here. dark-heart

The story is set during the Word Bearers' attack on Calth, and is designed to tie in with Dan Abnett's awesome Know No Fear. It features a certain young Word Bearer called Marduk  taking part in the attack on the Zetsun Verid Yard - and the subsequent counter-attack against the Word Bearers led by the big man in blue himself...

I've also written a short blog about writing this story for the Black Library site - check it out.
