A young winemaker. A devastating family secret. A truth that could destroy the man she loves.
Napa Valley, 1956: Winemaker Caterina Rosetta and her mother Ava harbor family secrets and face threats that could ruin their family winery, Mille toiles Vineyards. Concealing her husband's past in Tuscany, Ava Rosetta struggles to manage the vineyard, while her high-spirited, passionate daughter Caterina-a wine-blending savant-has inherited Ava's talent for crafting wine and guarding damaging secrets.
Caterina hides a truth that could ruin her in the eyes of her mother and traditional society: An illegitimate child. The father, Santo-Caterina's childhood best friend-abandoned her without explanation, leaving her with nowhere to turn. Devastated, Caterina journeys to their ancestral vineyard in Montalcino, Italy to claim an inheritance from her grandmother and seize the chance to start a new life. There, for the first time, she meets her unknown, extended family and discovers shocking secrets that could destroy the man she loves-who still loves her. Caterina realizes her happiness and the entire future of Mille toiles Vineyards depend on her ability to unravel the mysteries of the past-if she has the strength to face them.
