The thing that you really walk away form this story understanding is Vulkan is a life saver and not a life taker. He for lack of a better term is the most "human" of the primarchs. He is sort of the proof of nature vs nurture. He has great power and is a strong leader but not a tyrant because of it.

All in all it is a good story with some very enlightening moments about Vulkan's past and has enough twist to keep you interested throughout the book.

I give it a 3.5 out of 5
