From a bestselling Australian author comes a gripping novel of espionage, passion and sacrifice set in the Middle East during World War I.

Based on an astonishing true story, it asks what are you willing to die for? For readers of Geraldine Brooks, Heather Morris and Alli Parker.

During a train journey across Turkey's Anatolian Plain in 1915 during World War I, Shoshana Adelstein witnesses the slaughter of the Armenians and knows she has just come face to face with her destiny.

Convinced that her Jewish community in a small outpost of the Ottoman Empire will soon meet a similar fate, she is desperate to save her people. With Turkey and Britain locked in a global conflict, she orchestrates an audacious plan. Enlisting a group of co-conspirators who include her charismatic lover Eli and her impetuous brother Nathan, this young woman forms a clandestine spy ring. Conquering almost insurmountable obstacles, they risk betrayal, torture and death to spy on the Turks and pass on intelligence to the British to help them win the war.

This epic novel explores the fate of ordinary people whose mission collides with the secret agenda of powerful countries, people ready to risk everything to rescue their communities. But can individuals affect the fate of nations? And when life is at stake, how far will we go to reach the limits of our dreams?
