When Elise Beckett's long-distance beau, Stuart, offers her a dream job in organic horticulture research, she's torn between the opportunity of a lifetime and her responsibilities at her family's River Bend vineyard. But before Elise has time to make her decision, Uncle Edmond—the family's money-loving and temper-toting black sheep—is found dead on vineyard land. What seems to be an accidental drowning proves to be murder, and every Beckett, even Elise, is a suspect.

Sheriff's Deputy Jackson Landry must catch Edmond's killer, and Elise is determined to help him—whether he wants her to or not. Delving deeper into the mystery, Jackson and Elise become tangled in a long vine of suspects and dark secrets. Now a race is on for them to stop the deadly plot before the murderer claims another victim.
