Query: What a disappointment!!

I loved the first three books in this series. I could not wait for Feast of Crows to come out. After the first 50 pages, and nodding off several times I knew something was wrong. Simple put, it was boring. The author seems to have lost his voice and intensity. The characters lacked action, interest and engagement. They were flat and the plot wandered around aimlessly. I forced myself to finish when I realized there was another book coming out. Also, I was hoping that it would pick up.Save yourself some cash borrow it from the library or just skip it and go with Dance of the Dragons.Oh, I don't buy blaming the publisher. The author needs to control how his material is released and this book stands on its own merit not what it could have been or how it is related to the next book.
