I was on Amazon a moment ago and was recommended to buy 'Mark of Calth' a Horus Heresy novel available on Pre-order with no product details other than it being in paperback and its publishing date is 13th August 2013. I searched on the Black Library website and could find no sign of this book. Does anyone know anything else about it? I've seen the artwork before but not heard anything about the book!
I'm hoping it is a direct follow up to Know No Fear and will tell us what happened to Remus Ventanus and the other Ultramarines as they are forced to go underground to avoid the storms raging on the surface.
