Many authors have wondered what the world would be like if something big happened and the world changed. Many of the future earths imagined are rather bleak and more about survival then creating new futures. S. M. Stirling has a different viewpoint. When the Change happens to our characters in the Pacific Northwest, they see a dazzling flash of light, and find that higher technologies stop working, such as electricity and combustion engines. Chaos, disease, accidents, and hunger mean that a year later many people have died. The people still living have mostly gathered in small communities where archaic ways of life have become popular. Medieval history professor Norman Arminger takes charge of Portland, creating knights and serfs. Musician Juniper MacKenzie moves to her uncle’s farm and ends up chief of a Celtic clan which practices Wicca and trains youth in archery. College faculty form a democracy, and a monastery becomes a Catholic stronghold. A pilot with a teen passenger who’s a Tolkien fan become leaders of the Bearkillers and Rangers. Three books, starting with Dies the Fire, describe the development of the new societies. Another series, starting with The Sunrise Lands, tell the story of those leaders’ grown children and their quest to travel across North America fighting villains and bringing communities together. The characters are realistic, the author’s imagination fascinating, and the unfolding story lines and curiosity about the future engaging, as is the question of why and how the Change occurred and if a mystical sword will change things back.
