I have always been intrigued with the Dyatlov pass mystery, so not much in this book was news to me. With that aside, I really enjoyed this book. It’s easy to forget that these were real people with lives and families and I think the narrator did a great job bringing them to life. 
I don’t 100% ageee with the theory he ends with, although I do think it’s entirely possible, I was hoping for a more conspiratorial theory, I guess to keep it more exciting. But either way, it was well researched, he put a lot of time into it and wrapped it up very well to where I can actually imagine what their last hours were like.
