Book excerpt: After several visits to study Icelandic sagas, Nancy Brown returns to Iceland to search for the perfect Icelandic horse, one she can bring back to her Pennsylvania farm and make her own. To do so, she must become part of the country's tightly knit horse-breeding community, which can be wary of outsiders and extremely protective of the world-famous breed. In this clear-eyed, evocative account set against Iceland's austere and majestic landscape, she describes what makes Icelandic horses and their owners so distinctive. She also discovers her limitations as a horsewoman and learns much about what she is looking for-in a horse and in her life.
