Feeling scared and powerless when her father's anger escalates and her parents separate, twelve-year-old Anna has come to Rosemont to stay with her grandmother, Mim, hoping to forget her worries about her parents' troubled marriage. She'll be busy with the town's annual Flower Festival, a celebration with floats and bands that requires weeks of preparations. But before long, Anna finds herself involved in a very big problem when she sees a girl who looks like she's being held against her will. Anna can't forget the girl's frightened eyes, and she is determined to investigate. "When you see something, say something," she's been told, but what good does it do to speak if no one will listen? A take-charge girl like Anna isn't going to give up easily.
