Blush by Jamie Brenner

Vivian and her husband Leonard, started Hollander Estates winery on Long Island fifty years ago. Their children, Asher and Leah grew up among the grapevines and Leah's daughter, Sadie, also has memories of her childhood spent there. However, Hollander Estates is in financial trouble and Leonard says the family has no choice but to sell. Vivian and Leah are heartbroken when they hear the news, especially because Leonard has made all the business decisions over the years, not wanting to take any advice from either of them. In fact, years ago Leah wanted to help her father run the winery, but Leonard chose Asher instead.  Will the women be able to persuade Leonard to listen to their ideas, which may save the winery? Blush is a novel of the bonds between mothers and daughters, in addition to lots of details about wine and winemaking.
