Hannah Holmes is the author of four books ranging in subject from a natural history of dust, to the evolution of diverse, human personalities. Her accessible and humorous science writing is widely translated, and frequently used in classrooms. A Maine native, she began a freelance writing career while at the University of Southern Maine. After a stint as a magazine editor in New York, she developed a freelance specialty in eco-travel and science. An early contributor to The Discovery Channel Online, she participated in a number of pioneering media adventures, including “web TV” broadcasting, themed blogging, and live blogging from a series of far-flung and inconvenient scientific expeditions. Her writing clients have also included National Geographic, Discover, and The New York Times Magazine. Lately, however, Holmes has made a profession of her long-held fascination with human shelter. Her real estate clients have included a wildlife rehabilitator seeking three bedrooms, two baths, and accommodation for a ten-foot alligator. She lives in South Portland with her family.
