Kit Raine, an American writer living in Tuscany, is working on a biography of her close friend, a complex woman who continues to cast a shadow on Kit's own life. Her work is waylaid by the arrival of three women--Julia, Camille, and Susan--all of whom have launched a recent and spontaneous friendship that will uproot them completely and redirect their lives. Susan, the most adventurous of the three, has enticed them to subvert expectations of staid retirement by taking a lease on a big, beautiful house in Tuscany. Though novices in a foreign culture, their renewed sense of adventure imbues each of them with a bright sense of bravery, a gusto for life, and a fierce determination to thrive. But how? With Kit's friendship and guidance, the three friends launch themselves into Italian life, pursuing passions long-forgotten--and with drastic and unforeseeable results.
