I like extremes: Science and sagas. History and fantasy. The Dark Ages and modern times. Fire and ice. My books combine extremes: medieval literature and modern archaeology, myths and facts. They ask, What have we overlooked? What have we forgotten? Whose story must not be lost? For 20 years, I worked as a science writer at Penn State University. Now I live on a farm in Vermont with my husband, the mystery writer Charles Fergus. Icelandic horses graze outside my windows, and every summer I travel to Iceland in search of inspiration.
