Thessaloniki, 1917. As Dimitri Komninos is born, a devastating fire sweeps through the thriving Greek city where Christians, Jews and Muslims live side by side. Five years later, Katerina Sarafoglou’s home in Asia Minor is destroyed by the Turkish army. Losing her mother in the chaos, she flees across the sea to an unknown destination in Greece. Soon her life will become entwined with Dimitri’s, and with the story of the city itself, as war, fear and persecution begin to divide its people.
