Still the most exciting thing to be kicking off this year, in my opinion. Horror is sadly too often absent from 40k, or just too blunt to be effective. Anything that brings that out and gives people like Peter Fehervari a chance to shine is fantastic news (although Fehervari has a non-WHH novel coming anyway).
Agreed, Peter Fehervari captures the horror of 40k pretty well in his novels. As you said in many novels the grim and dark aspects are either overdone which causes it to lose all impact or toned down to sell the imperium as "heroes."
