I confess I'm not a great lover of his. I quite liked the first Estorea book but as with WP the second was not as good as the first.
I have read the first two of the Raven books but wasn't motivated to continue with them. Although the pace was good for S&S style fantasy, I found them filled with implausible situations, decisions, actions, motivations etc. They also had some dreadful inconsistencies. For example, there were maps provided, which is fine but he needs to use them more consistently. The whole bunch would travel from A to B on foot as fast as they. Then later they'd travel a shorter distance from C to D on horseback, again in a hurry, and yet take longer. These kind of things drag me out of the story in frustration.
So I'm afraid he's a thumbs down for me. Not a mega thumbs down but he was really part of my disillusionment with fantasy a couple of years ago, along with (and I'm sticking my neck out here) Eddings, Hobb, Feist and Brooks. I started finding so much of the mainstream fantasy too formulaic and the Raven books were no exception for me (despite the excellently created dragons). The Estorea books were a little better.
Probably just me not liking that style of fantasy, though I did find Abercrombie much better.
