First, three stars is only for this book. The series is so unique, dark, twisted and all things depraved. Ten stars at minimum. But though this was all those things it lacked the heart of the previous books. And I guess the editor was on leave. This author will always be favorite and a given one click. Still, this was a bit of a disappointing end to such a one of kind, like no other work. So, meh.
