"Chinese commandos in a lightning raid have seized the vast, under-populated, resource-rich lands of Northern Australia. Thousands of Australian soldiers are held hostage. International realpolitik has left Australia abandoned by its supposed allies and its brittle social fabric is rapidly unwinding as the people panic. A Chinese ultimatum demands the annexation of the country's top half in ten days, or face a full scale invasion. As other politicians clamour to sue for peace, Prime Minister, Gary Stone, in a desperate race against time and impossible military and political odds must commit to a risky and controversial plan to try and free the country"--Publisher's description.
