[also posted for The Wise Man's Fear] This is a great series. I read The Name of the Wind and then The Wise Man's Fear back-to-back. Having plowed through all of George Martin with similar enthusiasm, I enjoyed the more straightforward plot line. While Rothfuss got a little distracted with irrelevant detail, he overall kept the story moving and engaging... five stars.
If you've ever read The Pillars of the Earth, this is similar (with the obvious transition from historical fiction to fantasy). It is a story about people and how they grow, but set in a world called Temerant. Definitely in my top 10 list.
Here is what I didn't like: there is no third book. As others have said, I would have preferred to wait if I had known - I'm stuck here two books in and I'm only 2/3 of the way through the story. Since it is a framed tale, it starts at the "end", which gives the reader a persistent glimpse to how things might conclude... that makes it worse - you sort of know what is going to happen at the end, but not really. And apparently Rothfuss isn't in a hurry to finish his work. The Wise Man's Fear was published in 2011, and we are still waiting.
Patrick Rothfuss, you need to get this sucker done! Don't pull a George Martin on us. You are better than that (and unless something changes, you don't have HBO to help). So stop aiming for perfection and ship it!
