Ben Counter is a lifelong gamer and miniature enthusiast living in the UK, near Portsmouth. He is best known for his series of novels for Games Workshop including the Grey Knights and Soul Drinkers series, and has also written supplements for roleplaying games including Dark Heresy, Warhammer Fantasy Roleplay and World of Darkness. He is a founder of Death Spiral Games, publisher of the RPG Sleeper- Orphans of the Cold War.

Trademarks of his fiction include flights of Moorcockian strangeness, gruesome horror, blood-spattered action scenes and stratospheric body counts. A connoisseur of creative ways to waste time, he is a passionate (and, he likes to point out, award-winning) miniature painter, as well as a regular at his local game shop where he can be found playing miniature wargames, refereeing tournaments of Magic- the Gathering or running RPGs.

Evan Dicken has written the short story 'The Path to Glory' and the novella The Red Hours for Black Library. He has been an avid reader of Black Library novels since he found dog-eared copies of Trollslayer, Xenos and First and Only nestled in the "Used Fantasy/Sci-fi" rack of his local gaming store. He still considers himself an avid hobbyist, although the unpainted Chaos Warband languishing in his basement would beg to differ. By day, he studies old Japanese maps and crunches data at The Ohio State University.
