When Yulven unearths an enchanted atlas in his grandmother's attic, he and his friend Pirana unlock a series of golden riddles that whisk them, night after night, into dream-worlds across the globe. From paddling through Costa Rica's emerald rainforests to diving the Great Barrier Reef, they meet canny guides, decode ancient symbols, and learn how rivers, mountains, deserts, and cities shape human stories. Each glowing pathway on the map brings geography lessons alive in vivid adventures. At journey's end, they discover that the greatest marvels lie not only on distant shores but also in the hidden treasures of their own hometown.
