The lost vintage : a novel / Ann Mah.

"Sweetbitter meets The Nightingale in this page-turner about a woman who returns to her family's ancestral vineyard in Burgundy to study for her Master of Wine test, and uncovers a lost diary, a forgotten relative, and a secret her family has been keeping since WWII"--

Kate’s life as a sommelier in San Francisco is far removed from the French vineyard her mother turned her back on a generation ago. Her shaky knowledge of Burgundy vintages has been acceptable, but as she faces her final attempt at passing the notoriously difficult Master of Wine examination, Kate decides to return to the vineyard to help with the harvest and study the local wine. Then Kate discovers a secret room in the basement of the vineyard house containing World War II Resistance pamphlets, a stash of invaluable wine, and the belongings of a long-lost great aunt who was a teenager during the Nazi occupation. As she learns about her family’s life in Vichy France, Kate becomes consumed with discovering who her family aided during the war. -- adapted from amazon.com
