Twelve-year-olds Caelith and Remora earn a spot in the Guardians Scholarship, a summer program dedicated to preserving the world’s most treasured landmarks. From Machu Picchu’s ancient terraces to the Great Pyramid’s hidden chambers, Stonehenge’s solstice stones to Petra’s rose-red canyons, they learn hands-on conservation under experts like Dr. Yadrian. Each monument reveals new mysteries—cracks to repair, hieroglyphs to document, and cultural stories to honor. Their journey spans continents and centuries, weaving history, science, and friendship into an epic adventure. Back home, they transform discoveries into a digital archive, ensuring future explorers can keep the voice of every ancient stone alive.
