She's broke, barely able to make ends, meet while drowning in her late mother's medical bills and reeling after a one-night stand with her ex-boyfriend, who has now completely ghosted her. Enter Johnathan Aster, world-renowned photographer, with a proposal: he has a never-before-seen photograph of a woman falling from a train bridge, clutching what appears to be a baby. And he wants Julia to research the story.

Alternating between present-day Brooklyn and Kentucky as it enters the 1960s, the story unfolds as Julia races to find answers: Who was the woman in the photograph? Why was she on the bridge? And what happened to the baby?

Each detail is more propulsive than the last as Julia unravels the mystery surrounding the Fairchilds of Gray Station--and discovers a story more staggering than anything she could have imagined.
