The Provence Cure for the Brokenhearted by Bridget Asher

Second Hand 

'Every good love story has another love hiding within it.'

Brokenhearted and still mourning the loss of her husband, Heidi travels with Abbott, her obsessive-compulsive seven-year-old son, and Charlotte, her jaded sixteen-year-old niece, to the small village of Puyloubier in the south of France, where a crumbling stone house may be responsible for mending hearts since before World War II.

There, Heidi discovers a shocking secret and 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. Can the magic of the house heal Heidi's heart, too?
