The mountains hide many mysteries, and after a tragic collapse that took the lives of the members of the expedition “In the Wake of Bazhov,” there were even more of them. Masha Zvereva survived. For a whole year she was considered dead, but one day she was found in the mountains. She doesn’t remember what happened to her, yet she is firmly determined to uncover the truth about the causes of the disaster. Maybe it was her boyfriend, who organized the expedition—and saved himself? Or perhaps the dark-haired handsome man with amber eyes, who stirs in Masha a vague feeling of recognition? Or maybe it’s the work of the mistress of the Copper Mountain herself, whose image Masha sees in mirrors?
