This series isn't for the faint of heart or the weak of stomach, but if you can handle a certain amount of gore and disturbing content, you will be well rewarded. The mystery and the scientific intrigue are well constructed. The protagonists are damaged but worth rooting for, and there's always a surprising twist around the corner, although there is an apparent moment of danger near the end that seemed too easily dismissed. I look forward to the next in the series (which is obviously coming), and if any of his earlier books should be translated into English I expect I'd be pretty happy with them, too.
Overall: A
