This is the best book in the primarch series so far. I like the writing style of the author, and the story is nice in that it not only shows us what kind of a man the Primarch of the Word Bearers is, but also how he became this kind of person. Interwoven are little chapters that show the transformation of the legion after them being reprimanded on Monarchia. Sadly the plot is quite straightforward with almost no twists and turns happening in between.
