The Yard Between Us. Hollow Brook Wives, #7

Every house has a history the deed doesn't mention. Commercial appraiser Erin Cole makes her living looking for structural flaws. But when she and her husband Ben buy their dream home in the idyllic, manicured suburb of Hollow Brook, she misses the biggest red flag of all. It starts with a storm. When a violent nor'easter tears down the privacy fence between Erin's property and her neighbors', it reveals something buried directly beneath the property line: a hidden concrete storm cellar.
Inside, Erin finds a child's forgotten toys, a disposable camera, and a calendar from 2003 marked with a chilling code in red crayon. It's the exact summer eight-year-old Sadie Marsh vanished from the neighborhood without a trace. As Erin uses her professional skills to investigate the cellar's dark history, the tight-knit community of Hollow Brook closes ranks. Her inquiries are met with hostility, closed doors, and anonymous threats.
But the most terrifying discovery isn't what happened to Sadie twenty-three years ago. It's the trail of extortion, wire transfers, and lies leading directly back to Erin's own kitchen. Her husband knew the cellar was there. And he knows exactly where Sadie is now. Caught in a suffocating web of gaslighting and coercive control, Erin must secretly build an airtight case against the man she married-before he realizes she's stopped being his wife and started being his investigator.
