Ok, I know you don't want to post any spoilers, but how dark is this book? I keep reading reviews that say things like "what before was clearly black and white is now reveled to be shades of gray," and that has me a tad worried. I suppose I’m just too vanilla, but I like clear delineations between good and evil (unless the genre demands otherwise). I’ve heard that the books are intentionally getting “darker”, and this has been true for the previous four, but how dark is this one, really? I can handle a little political conflict and grumbling within the ranks, but if Harry starts having to engage in questionable behavior I’m going to be pretty disappointed.
