A heart-wrenching mystery about sisters, lovers, and a dinner party gone wrong.

Twenty-five years ago, a young girl left home to walk to school. Her younger sister soon followed. But one of them arrived, and one of them didn’t.

Her sister’s disappearance has defined Willa’s life. Everyone thinks her sister is dead, but Willa knows she isn’t. Because there are some things that only sisters know about each other—and some bonds only sisters can break.

Willa sees fragments of her sister everywhere—the way that woman on the train turns her head, the gait of that woman in Paris. If there’s the slightest resemblance, Willa drops everything, and everyone, and tries to see if it is her.

When Willa is invited to a dinner party thrown by her first love, she has no reason to expect it will be anything other than an ordinary evening. Both of them have moved on, ancient history. But nothing about Willa’s life has been ordinary since the day her sister disappeared, and that’s not about to change tonight.

Sarah Easter Collins has written an extraordinary novel about memory, lost love, and long-buried secrets that sometimes see the light of day.
