I agree with Sando. This series is awesome! The titles could be better, but the cover art is pretty cool. For example, the title here... The Crimson Campaign. Yes, it's a bloody war, but it doesn't really capture the vibe of the story. Regardless, I loved every minute of this book. The characters are well-developed. They all have their own unique personalities and relationships with each other. And the world and magic systems feel like they're so much bigger than what we see in this story. I can see why he chose to keep writing in this world after this trilogy. 

I'd say this series is a must-read for any fantasy fan. Highly recommended.
