In 1918, after the Great War, two Australian soldiers join the British army to help fight the Bolshevik forces in northern Russia. Almost a century later, two bodies are unearthed in the small Australian country town of Valley View. Following the Armistice, Sergeant Joshua Larkin is sent on a special mission deep into enemy territory in Russia. But when he is ordered to do the unthinkable, he must flee across Europe in order to protect a young woman, Maria, whose family has been executed. With Maria's life under threat due to her imperial connections, nowhere is safe. Decades later, the discovery of the two skeletons in Valley View poses problems for local policeman Morgan McLean. Who are the victims and why were they killed? Could the rumours of an heir to the Russian throne be true? And what explosive secret is Britain's MI6 desperate to keep hidden by any means necessary? Past and present collide in The Frozen Circle, and the fate of two people unleashes a volatile series of events that could reshape the world.
