I picked up the Khorne Daemonkin book - a digital copy - right when it came out. Although I have not traditionally been a Khorne player (says the guy with 36 Flesh Hounds, 2 Skull Cannons, 6 Bloodcrushers and 2 Heralds of Khorne), I really liked the integration I was seeing with CSM. For those considering the book - I highly recommend it if you are looking for a way to revitalize your CSM and add more depth/flexibility to a Daemon army. The fluff is a bit redundant - let's be honest, there is not a lot of depth when it comes to Khorne - but there are some cool stories and marking schemes to help differentiate squads. In this article I plan to cover the special rules in the book, and what makes it different from individual CSM/Daemons.
