A colorful book -- a well-sustained story for teen age boys and girls. The Merryweather twins face fairly substantial responsibility when they move from a comfortable New England home to make a new home for their ailing father on an Arizone ranch. Jean is at first appalled by the primitive conditions she must face; John almost thrown off balance at first by the demands of the new country, rises to his obligations as he grows into young manhood. They make a new friend in Nat; they meet unusual people, and take big strides toward maturity. And when opportunity offers for return to the east, the twins realize that this has become their country, that the future holds the answers to their dreams.
