Well laid out and told in an interesting manner. I went in only having read the Wikipedia article about the incident and having heard about it from my parents (who in turn heard about it from theirs as a cautionary tale), I learned a lot of new details about the case.

While I usually dislike switching timelines and perspectives, the method used here (switching between retelling of Dyatlov group's path, the investigation and the author's journey) worked quite well to keep my attention to the book.

I found the author's amazement over some Russian characteristics/traditions quite amusing.
