Dorthe Nors's first nonfiction book chronicles a year she spent traveling along the North Sea coast—from Skagen at the northern tip of Denmark to the Frisian Islands in the Wadden Sea. In fourteen expansive essays, Nors traces the history, geography, and culture of the places she visits while reflecting on her childhood and her family and ancestors' ties to the region as well as her decision to move there from Copenhagen. She writes about the ritual burning of witch effigies on Midsummer's Eve; the environmental activist who opposed a chemical factory in the 1950s; the quiet fishing villages that surfers transformed into an area known as Cold Hawaii starting in the 1970s. She connects wind turbines to Viking ships, thirteenth-century church frescoes to her mother's unrealized dreams. She describes strong waves, sand drifts, storm surges, shipwrecks, and other instances of nature asserting its power over human attempts to ignore or control it.

Through a deep, personal engagement with this singular landscape, A Line in the World accesses the universal. Its ultimate subjects are civilization, belonging, and change: changes within one person's life, changes occurring in various communities today, and change as the only constant of life on Earth.
