When Eirwyn and Calix uncover a pair of magical travel boots in Grandma's attic, they're whisked from Maasai savannahs to Florence's rooftops, through Vietnam's rice terraces, Colorado's peaks, and the heart of the Amazon. Along the way, they solve geographical riddles, learn cultural crafts—from Maasai beadwork to Dreamtime stories—and record panoramic sketches and climate facts. Each continent brings new friends, fresh challenges, and awe-inspiring discoveries, filling their leather journal with stamps and stories. By journey's end, the siblings return home brimming with global wonder—and their once-blank journal becomes a testament to the shared beauty of our world.
