As a forestry student doing an internship, Anja Grimm ends up in that remote area in the Upper Palatinate Forest, where she went on vacation with her parents as an eight-year-old girl and her father disappeared without a trace. Her job is to take soil samples to create a soil map. At one point in the forest floor she comes across abnormal irregularities. Not long after their arrival, a brutal murder occurs. Anja soon arouses suspicion and hostility not only among the villagers with her suspicion that the perpetrator knows something about her father's fate and with her questions about the atypical soil composition in the forest clearing. Even the police react extremely reservedly to their investigations. And when it turns out that the young woman can read the signs of the forest like an open book, forces mobilize in the village who are apparently ready for anything because there is a dark secret that needs to be kept.

A book, that attacks the reader's sanity - Severin's long-forgotten childhood angst. One night, all his fears resurface when he gets his hands on the dreaded pages, and every line seems to confirm his most powerful fears. Accompanied by the antiquarian Palatinus, Severin dares to read the book and delves into the alchemist's spell.
