Here's a book that was apparently written quite well, but was translated rather poorly. David Guymer did write a nice story that would fit in with of most books in the warhammer universe, however it's not how, in my opinion at least, a primarch series novel should be like. Too many perspectives, too little focus on Ferrus Manus himself.
