The subtitle of the book is “The true story of a woman who learned from Berbers to be just happy”. It took a while until she could be happy. She was cheated and it didn’t seem that her adventure in Marocco would be successful, but with a lot of endurance and will she built a new existence near Marrakech. I visited her garden “Le Paradis du Safran”. It is a paradise and Christine is a wonderful woman.
