Holly and Robert Barron are attractive young real-estate investors and contestants in a competition run by To the Manor Build, the nation’s most popular home renovation app. With millions in product endorsements and online followers at stake, they’re rehabbing a Vermont home they scored at a bargain price into a chic hilltop estate ideal for entertaining.

It’s all camera-ready laughs and debates over herringbone tile until Holly and Robert go missing hours after their picture-perfect wedding—leaving behind a bloody trail.

Suspicion falls quickly on Erika Turnbull, the Barrons’ twenty-something assistant—eager, efficient, and secretly in love with Robert. Did Erika let her misguided passion turn her into a murderer? So claim the townsfolk of Snowden, Vermont, who still haven’t forgiven her for a tragic accident back in high school.

But Erika’s mother, Kim, is not about to let small-town gossip and a cop with an axe to grind destroy her daughter—again. With time running out and their own lives at risk, the mother-daughter duo set out to find what really happened to the Barrons. First, though, they’ll have to confront the vengeful former owner of Holly and Robert’s estate, ruthless reality-show producers, and a secret that might bring their own house down.
