Léa Chrétien was born in France in 1986. In her childhood, she developed a passion for drawing and storytelling. A voracious reader, she devoured all kinds of books. She had a preference for detectives and fantasy novels but also for poetry or comics. After graduating in the visual arts, she went to Liège to study illustration at ESA Saint-Luc. At the end of her training, she was working on multiple projects of comic books, although none of them came to fruition. In the time following a trip to the southern states of the US, the idea for a new story began to sprout in her mind. Two years later, she wrote "Louisiana" (Dargaud; Europe Comics in English), with Gontran Toussaint as the illustrator.
