I've read both the Willden trilogy and Dralin. Both are good, but I agree with John that the writing in Dralin has improved considerably. I also liked following Ebudae and Pelya.
To me personally it feels like Dralin is skewed towards a somewhat older audience The Willden Trilogy felt a bit childish at times, but I liked it all the same
Can't wait to see what your next book will be John.
