The first half of the book is full of the promises one could expect after reading the first two : more clues, more local mysteries, more answers. I can't say I feel entirely satisfied, even though there's a lot of good moments. I can't say much about the second part without spoiling, but I felt it veered into horror a bit, and while the plot is extremely surprising, a bit of frustration lingers. I'll be looking for more answers in the fourth book I guess.
