I liked Ghost Story. I even like Skin Game. These last two books have about done me in for the series though, especially battle ground.
No need to rehash the many complaints in detail here...Murphy's death, Marcone, Nemesis, kind of the absurdity of this pseudo apocalypse...
Between the problems with these two books-that-should-have-been-one-book, the things that should have been fixed in editing and beta reading, the long-ish pause before them and the extra long lag in writing after them...and Butcher's personal life issues...I kind of thought he may have just decided to scrap the road map and call this the planned 3 book apocalypse. Sadly, not. And, I think there's a lot of those aforementioned personal problems and just struggling with staying focused writing coming through here. I'll give it one or two more books (since mirror mirror is likely to be entirely outside of continuity), but I'm likely done.
