Heart-Diamond describes the author’s experiences growing up on a working cattle ranch in Southeastern New Mexico. In a series of sketches that begins with an incident in her childhood and concludes with her return to the ranch after a lengthy absence, the book features various members of her family in settings and situations typical of daily life not only on the Heart-Diamond but on any small, family-operated ranch: rounding up cattle, fixing windmills, helping a heifer to calve. At the same time that the sketches celebrate western culture and the love that holds the family together, their touch is light and humorous. As a book written from a woman’s point of view, Heart-Diamond offers some unique commentary on the "cowboy" way of life.
