Things don't break on their own

Nobody ever found out what happened to Laika Martenwood, the girl who vanished without a trace on her way to school one morning. But for her sister Willa, life shattered into tiny pieces that day, and she has never been able to put them back together again. Willa sees Laika everywhere: on buses, at parties, in busy streets. It's been twenty-five years, and the only thing that has kept her going is her belief that her sister is alive, somewhere. But when a dinner party conversation about childhood memories spirals out of control, a shattering revelation from one of the guests forces Willa to rethink everything she thought she knew about her past.
