On his first morning at the Cannes film festival, movie critic Marcel Klein is starstruck – not by an actor, but by Héloïse, a beautiful woman with a troubling secret. Each time they meet – at press events, parties and premieres – they test each other's limits. But when Marcel's countless lies threaten to catch up with him, the two of them get in a car and leave Cannes behind, hoping to outrun the past. A deeply moving and fast-paced novel about love and lies.
