Written for middle-grade readers, 10 Routes That Crossed the World explores famous roads, trails, and pathways across the globe that have played a significant role in human history. Chapter subjects include the first crossing of humans into North America across the Bering Strait; the Camino de Santiago trail in Spain and its importance to pilgrims for centuries; how the Inca Trail in Peru helped both build an empire and facilitate its destruction; the war-torn Khyber Pass connecting Afghanistan and Pakistan; the building of the Trans-Siberian Railroad under extreme conditions; the short but treacherous Chilkoot Trail, which led hopeful gold prospectors to riches; and the Serengeti migration trail, traveled by millions of animals and Maasai people for generations. Dramatic fictionalized stories with accompanying artwork open each chapter, and colorful pages include a variety of archival and modern photos.
