I normally get through 2-3 books a week. This series took me 6 months. Huge, and hard reading - vast arrays of characters, many having more than one hard-to-pronounce name, most of whom have back stories that may be explained in detail, current and past character interactions & deeds have big effects on the current plot(S), sometimes.

I'm glad I read it, but I will never reread it, I burnt the copies and buried the ashes in assorted corners of the world in case I was ever tempted. Or I would have if I wasn't using eBooks.
