It’s the summer of 1892. A year earlier, Sofia and her friend Theo set off on a journey that was destined to rewrite the map of the world. But the girl never found her parents. And so, after a useless search in archives and libraries for at least some clue to the mystery of the disappearance of her father and mother, Sofia comes to the conclusion: an alien era holds the key to her search. Unexpectedly, she receives an anonymous invitation to the secret archive of the Nihilism sect, where she learns about the diary that her mother kept. The diary is located far away, in Granada, but not the Granada that is indicated on geographical maps, but in Granada, which lies in another era, called the Dark. And Sofia secretly goes in search of the diary... The book by S. I. Grove “The Golden Medicine” is the long-awaited continuation of “The Glass Map”, one of the best-selling books in the Amazon online store in the year it was published. The author of the translation of the novel is Maria Semyonova, creator of the famous series about Wolfhound and other famous books in the historical fantasy genre.
