Coauthored with Dixon, a children's book author (Blueberry Shoe), this exciting memoir recounts Flowers's 2,500-mile journey across the North American Arctic, undertaken at the age of 46. Retracing in reverse a 1924 expedition led by Norwegian explorer Knud Rasmussen, Flowers and her eight sled dogs mushed from Barrow, Alaska, to Repulse Bay in Northwest Canada, becoming the first woman and the first American to do so. Fulfilling a lifelong dream and driven by an adventurous spirit forged in childhood, she left her job as a respiratory therapist and began seriously training for the expedition in 1992; the trip began in February 1993. The sled dogs, for whom the author has "tremendous respect," ranged in age from one to nine years and spring to life through descriptions of their strengths and distinct personalities. Dependent on one another for survival, Flowers details the care she took to make sure the dogs received enough food, water, rest and love for each day's travel. She recounts how her lead dog, Douggie, was able to sense the right direction even when she could not. She and her dogs battled cold, wind, storms and exhaustion on the tundra. Their isolation was broken by brief visits with settlers in the small Alaskan and Canadian communities where they rested and Flowers picked up supplies. At one point, due to unsafe summertime sea ice, she briefly considered giving up. Instead, the team rested for several months in an Inuit village and successfully completed the expedition in January 1994. Color photos. (Oct.)
