Where does the writing begin? In the body or in the head? In the hand that holds the child's pen at the table or in the adult's memory? Maybe we need to look elsewhere. Find the tracks. Having fun with graffiti on the street. Observe the rituals of writers, those of yesterday (Proust, Walser, Benjamin) as well as those of today. Explore Mesopotamia, Greece, Egyptian myths. From personal memories, travels and artists' confidences, Sally Bonn composes the most sensitive piece of all: her book.
