What happens when fantasy is the only thing that seems real? Just a few months ago, Tom Boyd was a multi-million-selling author living in LA, in love with a world-famous pianist. But after a very public break-up he's shut himself away, suffering from total writer's block, with only drink and drugs for company. One night, a beautiful, naked stranger appears in Tom's house. She claims to be Billie, a character from his novels, who has fallen into the real world because of a printer's error in his latest book. Crazy as her story sounds, Tom comes to see that this must be the real Billie. And she wants to strike a deal with him: if he writes his next novel she can go back to the world of fiction; in return she will help him win back his beloved Aurore. What does he have to lose? Guillaume Musso's latest romantic adventure is a story of friendship, love and the special place that books have in our lives.
