During the Voss family’s livestreamed fiftieth-anniversary dinner at their glass lake house, Lena’s younger sister Elise vanishes mid-broadcast — and a twenty-seven-second feed delay proves she left the table before anyone realized.

A crisis-PR professional used to killing scandals for wealthy clients, Lena follows a trail of small objects, disused service routes, and doctored recordings while reporters, a fixated online watcher, and her own relatives each press a tidier version of events.

As the evidence points beneath the house and toward a long-buried connection to a clinic across the water, Lena has to decide whether protecting the family’s image is the same thing as protecting her sister.

Tropes: family secrets, missing person / disappearance, closed-circle mystery, hidden rooms and secret passages, estranged sisters, dying matriarch, domineering patriarch, ex-spouse forced back into contact, red-herring stalker / wrong suspect, institutional cover-up, race against the clock, unreliable family narrative
