- Nine-year-old Olivia Brown doesn't mind spending the summer at Aunt Lila's rural home, but she's tired of her brother Aiden's complaints. Shortly after their arrival at the old house on the Rappahannock River, Aunt Lila gives Olivia a key that will lead her and the Florida cousins to adventure, all without leaving Hull Crossing, Virginia and the nearby Northern Neck.
