It used to be just Lucy and Aunt Mary - now there's going to be four. When her aunt gets married and a new baby is on the way, ten-year-old Lucy is sure she's about to be replaced. Over one chaotic year of weddings, midnight cravings, and a baby sister who only calms down for her, Lucy discovers that a family growing bigger doesn't mean there's less room for her. A tender, funny middle-grade story about belonging, big sisters, and being chosen.
