Brokenhearted and still mourning the loss of her husband, Heidi travels with Abbot, her OCD eight-year-old son, and Charlotte, her sixteen-year-old niece, to a small village in the south of France, planning to renovate her family's crumbling stone cottage. There, Charlotte confesses a shocking secret, and Heidi learns the truth about her mother's 'lost summer' when Heidi was a child. As three generations collide with one another, with the neighbour who seems to know all of their family skeletons, and with an enigmatic Frenchman, Heidi, Charlotte, and Abbot journey through love, loss and healing amid the vineyards, warm winds and delicious food of Provence.
