Katharine Stewart lived on a croft with her husband and daughter for many years. Her experiences during this period of her life were recounted in A Croft in the Hills. She has since helped to set up a crofting museum next to her home near Loch Ness. Among her other books are A Garden in the Hills, describing the life of her garden during the course of a year, and A School in the Hills, about the schoolhouse in which she lives and the way in which the children of the Highlands have been educated over the years.
