🗺 The Cartographer's Daughter

In this evocative B1-level interactive storybook, 15-year-old Elena Marin finds a hidden note from her late father — a cartographer who spent twelve years mapping Venice's underground passages. His unfinished map leads Elena to Byzantine mosaics, medieval trading tunnels, and sealed chambers beneath the sinking city. With help from a marine archaeologist, she completes the map, fights a development company, and secures heritage protection for Venice's hidden world — while learning to carry her father's legacy forward.
