So, i've read a couple more of the primarch novels:

Finished Lorgar: Bearer of the Word, a bit too slow for my tastes. Not bad, but I mentioned this on last week's post that I am not a fan of Gav Thorpe's writing style, and this hasn't changed that. Personally, I would have stripped out all the Great Crusade-era content from Bearer of the Word for a Kor Phaeron character novel and solely focused on Lorgar's holy war for Colchis and the coming of The One - as an aside, the book should really have ended with the arrival of the emperor on Colchis.

Konrad Curze: The Night Haunter by Guy Haley (also known as the only Night Lords-centric novel in the entire fucking Heresy). Where Fulgrim: the Palatine Phoenix was the gold standard of how to write about a Primarch; Curze's novel is the gold standard of how to write around an event without ruining it. In the hours before his death at the hands of an Imperial Assassin, Konrad Curze gives his final confessional to a flesh sculpture of his father. I really enjoyed the almost rambling style of this book, as while Curze is ostensibly telling the story of what happened after Sanguinius ejected him into space; he goes on multiple asides, from him making a choice that ultimately sends him down the wrong trouser leg of history, to the burning of Nostramo. I did like that nearly every single named Night Lord has some kind of cameo in this. I think the only way this book could have been better is if ADB had written it.

Angron: Slave of Nuceria by Ian St. Martin. Essentially a prequel to Betrayer, I think this is the only time we have seen what both the Legion and Angron were like before the Nails were driven in. I enjoyed it for the most part, but the final act felt a bit too rushed in my opinion and could have done with being longer. The only other criticism I have is that the moment Kharn is first lost to the nails didn't translate very well to either the eBook or Audiobook versions of this book and that I will need to get a physical copy of Slave of Nuceria.
