It's been quite a while since I last read a book in the Dresden files, so one part of the experience was wondering what references I was missing and if I'd skipped a book or two since I didn't recall some significant previous events referred to in the book. (My records tell me there are no gaps in my reading though, just in my memory.) But it didn't matter much. I remembered enough and some gaps were filled in along the way and visiting the world of Harry Dresden again was enjoyable.
