Nina is a nobody.



She cleans other people's houses, drives a dying car, and goes home to a boyfriend who'd rather complete anonymous tasks for an app that pays cash and asks no questions. She has learned not to expect much from anyone.



Until the day she crashes into Florence.



Florence is wealthy, magnetic, and unsettlingly calm. She takes the blame. She offers Nina a job. She takes her under her wing. And Nina, who has never once been chosen by anyone, lets her. It is the worst decision she has ever made.



Because Florence's world has locked doors. The closer Nina gets, the darker it becomes, until one night something happens that binds them together in a way that cannot be spoken of, reported, or ever undone.



But someone knows.



Someone who has been watching far longer than either of them realize, piecing together every lie, every loose end, every moment they thought they were safe. Someone who will stop at nothing to expose them both, and doesn't care how much damage they do in the process.
