Guillaume Musso, the No. 1 author in France for the twelfth consecutive year according to Le Figaro, signs a groundbreaking story covered with a dose of love and mystery. They wrote about the book: "Guillaume Musso is rightly the master of suspense." –Le Figaro "A novel that can be read in less than 24 hours and it would be criminal to reveal the ending." –Marianne Payot, L’Express "Intelligent and with a dizzying pace. It's very hard to put it down before reaching the end. Perhaps his best book so far." –Jerome Vermelin, Metronews
