I'm reading the fifteenth book in the series and decided to write the first review, not on this book but on the series in general. I've read a few comments and they are all undeniably true. The fact is that you either love or hate a series of books like this. Obviously many situations may appear repetitive, basically it is the story of a profiler who finds serial killers, it is true that in all the books there are boring repetitions (such as the purpose of the HSS - Homicide Special Section, the description of the physical traits of the characters , some details of their past, etc...), I believe to ensure that the book can be read stand alone having a minimal conception of the background story. Personally, what I particularly like is the description and psychological evolution of the characters. This makes books enjoyable in my opinion, so far I haven't gotten bored yet and I'm moving forward with reading. Don't expect to find a treatise on psychotherapy, this is not the purpose of such a book, but for an average reader like me, the work done by the writer is appreciable. I'm a lover of thrillers, so I also like the part purely concerning the investigation, I find it to be written in a very pleasant way, even if it doesn't reach extreme heights. To conclude: would I recommend it? The answer is yes
