But determination, hard work and a little luck see them begin to establish themselves ... until circumstances deal a shattering blow that forces them to consider life’s priorities. Weighing up their options they decide to leave Coober Pedy and with nothing more than a vague plan and the support of the vivacious and spirited Naomi Wilson, they saddle up their stock horses and head for the Northern Territory – and an uncertain future. But then a chance discovery presents them with an opportunity that will change the course of their lives for ever.
