After La Nuit de feu, where Eric-Emmanuel Schmitt described his mystical experience in the Hoggar desert, he returns to his sources with this travelogue in the Holy Land, a territory with a thousand imprints. Bethlehem, Nazareth, Caesarea, intense and cosmopolitan places that he captures on the spot while deepening his spiritual experience, his questions, reflections, sensations, astonishments until the final surprise, in Jerusalem, of an incredible encounter with what he calls "The incomprehensible".
