Yes, I have and I love it - it's my favourite of the four series by her I've read. It starts a little slow; the first couple of books are good, but subsequent books just get better and better. I highly recommend it. Its characters are at least as richly written and the plotting is more intricate, more complex, and the world building is closer to the realm of plausibility (sort of). The humour is better too, I think. Definitely give it a try if you enjoyed this one.
