Nora Hayes rebuilt a 1971 Dodge Challenger with her bare hands. She raised a boy who wasn't hers by blood, kept a house that wasn't hers by law, and never left, not when his father walked out, not when the money ran thin, not when fifteen years of sleeping alone turned her body into something she'd stopped thinking about.

​

Jake is twenty now. He's back from a relationship that taught him what love isn't. And when he looks at the woman who raised him, really looks at her, he sees what he's always known but never had the courage to say.

​

She taught him to cook a steak. To drive a car, she built from nothing. To stay when staying is harder than leaving. Now he wants to learn something she never planned to teach him.

​

One night, in the house they've shared for seventeen years, the line between family and something else disappears. And neither of them wants to find it again.
