Das Vermächtnis des Alchemisten

The historical backdrop adds so much flavor to the story. I'm curious whether the author did specific research or if it evolved naturally during writing.

The puzzle-solving moments really kept me on the edge of my seat. I wonder if those clues were planned from the start or came together during editing.

Their camaraderie added warmth and humor, but I also noticed some tension. Did the author intend to explore different types of bonds in a middle-grade adventure?
