It is 1972 and James and Katrina Martin set off for a well earned month of vacation from Zambia to South Africa and England. They return to find that James is to be offered an opportunity to start a new mine away from the Zambian Copperbelt, an opportunity that he takes. They travel to the Mtuga operation which is located just off the Great North Road in the Mkushi district of Zambia. The mine is sited on old workings from the 1920's and is being re-opened as a surface mine. The Mkushi District is better known for its tobacco and maize farms and in the late 1970's for the camps of the Zimbabwe People's Revolutionary Army (ZIPRA), an organization that they will encounter a few times.
Life is complicated when the Rhodesians close the border with Zambia and Zambia retaliates, potentially stranding all their new mining machinery outside the country. They must formulate a plan to get everything to the mine and the operation started on time and to budget. Things are further complicated by corporate politics and rivalries that create problems along the way.
Although now married for almost three years, James and Katrina continue to discover each other and their romance and desire for one another is as strong as ever. They take every opportunity they can to be away and alone together in the more remote parts of Zambia.
