After their mother dies, Haidie Richards and her younger brother, Boots, are put to work in an orphanage. Their father left four years earlier to find a gold mine in Colorado Territory, and since then he's sent only three letters. Still, Haidie is certain that he is alive, has struck gold, and will soon send for them. But patience is not one of Haidie's virtues and soon she and her brother make a break for it. Boots and Haidie, disguised as a boy, embark on a dangerous journey deep into Western territory. Along the way, Haidie learns fast not only how to handle mules, oxen, and greedy men, but also that you are better off in a community. Hers includes a card shark, independent "spinster" sisters, and a very fierce dog. Once she arrives in Colorado and finds out the truth about her father, Haidie will need all her new friends for a get-even plot worthy of The Sting.
