Interesting you've mentioned that, I just finished "Broken Empire" trilogy a week ago. Dunno really, I' wasn't that much impressed with it, as many people are. Somehow I found it repetitive, with a lack of character's development. And I must admit I'm not a fan of epic fantasy/sci-fi crossovers. I had a same problem with "The Book of the New Sun" by Gene Wolfe, and Lawrence did similar thing. Although, overall it was fast pacing and good read, but not near to some of the big names in grimdark genre. Just my opinion.
