Theodora Klaven is thirteen when her older brother Josh disappears. He’s long threatened to run away, and one night, while they’re out drinking in the woods, he hops on a late-night train to Manhattan and leaves her behind. Her family shattered, Thea is left holding onto her incomplete memories of that night, still hoping for an answer.

Now twenty-six, Thea is a rising art gallerist in New York with a steady fiancé and a coveted promotion within reach. Then Marin—Josh’s old girlfriend and the last person to see him—walks into the gallery. She’s older, sharper, and just as compelling, with a photography portfolio Thea can’t ignore, and a shared history that tugs at an unhealed seam.

Thea throws her support behind Marin’s work, convinced she’s found the breakout artist she’s been looking for. But she also suspects that Marin knows more about the night of Josh’s disappearance than she lets on. As their relationship intensifies, Thea’s carefully constructed life begins to unravel.

When a catastrophic revelation forces her to question everything she thought she knew about her brother, she must decide what she wants from the past—and what kind of future she still has the power to choose.
