Behind Enemy Vines by Marysa Stevens:
 
Event planner Stori McKinsey has spent years building her perfect life—luxury apartment, high-profile career, flawless image, impeccable wardrobe. Then, in the span of a single disastrous week, her ex-boyfriend steals her promotion and accuses her of attempted murder, and her estranged grandmother, Verna, dies.

At the behest of her eccentric mother, Stori reluctantly agrees to head to small, rainy Pear City for the reading of Verna’s will. What Stori expects is a few signatures on behalf of her mom and a sense of closure; what she gets is half ownership of Flights and Feathers, her grandmother’s struggling boutique vineyard.

The other half belongs to Seamus Truett: high school chemistry teacher, volunteer firefighter, and the kind of infuriatingly decent man Stori can’t stop clashing with. Seamus is determined to save the winery and honor Verna’s legacy, even as Stori searches for any escape route she can find.

Immersing herself in Verna’s world unearths old conflicts and trauma Stori has long buried. Verna’s complicated legacy continues to uproot Stori’s life in unexpected ways, tying her closer to Seamus, but suppressed secrets threaten to pull them apart.
