Anthony has always known he was born through anonymous birth and has never felt the need to seek out his biological mother. Until the day when a minor administrative detail, discovered at the birth of his first child, shakes the very foundations of his life story. The author, a philosopher who has always sought to explore truth, dares to turn toward the most radical doubt and the quest for his origins. A powerful reflection on identity, abandonment, loss, and faith, and a deeply moving text about the relationship between children and their parents.
