Lana Burrell grew up on an idyllic Napa Valley vineyard with her best friend Jess - until Jess mysteriously disappeared and Lana's father was falsely accused of her murder. Over twenty years later, he's still serving a life sentence, but Lana knows he's innocent, just like she knows Jess's real killer is still out there. Now, as a seasoned FBI agent in the San Francisco field office, Lana figures she can handle just about anything - until a killer strikes the Valley again and those old wounds come bursting open. Two women are slain in ritualistic fashion near the vineyard she once called home, and Lana has no choice but to revisit the site of the nightmarish past she tried to leave behind. A past that seems to be repeating itself as the blood and wine continue to spill all over Napa Valley. With rumours of a dangerous cult embedded at the centre of wine country, the most powerful family in the Valley breathing down her neck, and a mysterious stranger stalking her every move, Lana's quest to solve the murders takes an even darker turn when she soon realizes the awful truth: she might be the next to die.
