So I completed Sons of Dorn* and Rynn's World** about a week ago and they (mostly Rynn's World) blew my mind apart. The Crimson fists are hands down one of the most respected and fearsome chapters in all of 40k. The book was riveting, action-packed, and well worth $12. As for the Sons of Dorn... it was good. It was mostly about scouts, their training and recruitment in to the Imperial Fists Chapter, and their struggle to fight the enemy without killing each other out of hate. I look forward to seeing more in their series but I would recommend borrowing it from some who bought it because while it was good, it seemed lacking to some extent.
*Sons Of Dorn [8/10]
**Rynn'sWorld [10/10]
On a different note, I just recently bought Salamander, Storm of Iron, and Helsreach and have finished the first two. I will review those later.
Until next time... Ave Imperator.
