Query: great book yet too slow

this book was great.The one thing that really bothered me was that at times the detailes were being dragged out and making it very frustrating to read. I was quite satisfied with the ending although i am usually very specific about endings. i hope that if tanith lee writes a fifth book it will end any further questions and not be quite as confusing
