I wanted to go as far as possible with the published books, and this one got back on the main plot with a lot more to learn, deduce, suspect and guess. The writer said she was working on the following ones, so I can leave the series for a while and be on the lookout for the next one when it's published. All in all, the whole series is really worth the time, even though it's a bit long sometimes, everything matters, all the details build up an very interesting universe, with its people, customs, landscapes and monsters of all types... it's pretty unforgettable.
