France, 1714. In a moment of desperation, a young girl makes a deal with the devil. She will live forever, but at a price: anyone who knows her will forget her in an instant. And so begins the adventurous and paradoxical life of Andy Larie. As a young woman, she travels across continents and centuries, exploring art and history, pushing the limits of what she is capable of in order to leave her mark on the world. But everything will change, almost 300 years later, when Andy unexpectedly meets a young man in a remote bookstore, and he will not forget her name.
