I like extremes: Science and sagas. Science and faith. History and fantasy. The Dark Ages and modern times. Fire and ice. My books combine extremes. They ask, What have we overlooked? What have we forgotten? What knowledge must not be lost? For 20 years, I worked as a science writer at a university. Now I write from a farm in northern Vermont, where the days are quiet and cool. Four Icelandic horses graze outside my office window. Every few years I take an adventure--and write a book about it.
