In the first book of the series, "A Duck in the Desert," Pepe Quackamole, a sombrero wearing, scarf-toting, rubber duck, first encounters the Southwest when he finds himself unexpectedly lost in the desert. With a water-shy, desert frog named Fred as his guide, the two new friends embark on a journey that takes them through the desert's many wonders and strange sights in their quest to reach the waters of Oak Creek in Sedona, AZ.
