Paris (CNN) -- France's ex-First Lady, Valérie Trierweiler, is back with a vengeance. A few hours after her memoirs of her relationship with President François Hollande, called "Merci pour ce moment" (Thanks for the moment) hit the bookstands in France, a new poll showed that the President's approval ratings were in free fall, reaching the historical low of 13%. Some extracts had been leaked to the press the day before and Paris Match, Trierweiler's employer, had exclusively revealed the "best pages," or rather the most damning pages about the President. On Thursday evening, her publisher revealed that in just a few hours of sales, her essay was doing three times better than Fifty Shades of Grey when it was launched. On Amazon, her book was selling like hot brioches, with one copy sold every five seconds.
