Those who love Marc Levy love Guillaume Musso. They share the same talent to tell a story and seem to apply the same recipe: take a well-paced story. Take everything with a touch of the supernatural and expatriation strand made in USA. Sprinkle all with a dollop of romance. Mix everything. Shake. Let mount the reading pleasure. Enjoy. "And then ..." deserves its success in bookstores. A book to recommend to those who did not want to take the lead and want to have a good time.
