Yiorgos Doukarelis, an archaeologist and professor at the University of Athens, returns to an island in the Small Cyclades, Koufonisi, 20 years after the excavation that made him famous and changed his life forever. At that excavation, he discovered the prehistoric remains of a young pregnant woman murdered 5000 years ago. They gave her the name Kassiopi. During this trip, he had an affair with one of his students, Antigoni. They got married after Yiorgos’ divorce from his former wife Maria.
He returns to the island, six months after Antigoni disappeared mysteriously. The order and the routine of his daily life are destroyed. He is left with his memories and the only person close to him is his daughter Ismini. Going around the island, roaming the places he lived during the time of the excavation and meeting people from the past, he also wanders through his memories, exploring the secret ties that connect him with the three women of his life, moving from the present to the past. This is a second excavation for him, an excavation into the deepest places of his soul. He tries to remember and put in order all that happened during that summer which had a decisive impact on his life. In his fantasy, Doukarelis goes back to the prehistoric times of Kassiopi, recreating the story of the murdered pregnant young woman.
This diary of an infidelity is also a novel about time, destruction, memory and love, which balances the present and the past.
