De sleutel van Sleedoorn

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?
