She is the only child of Reg and Ivy Whittacker, who neglect her despite the fact that she is pretty, clever, and imaginative. She is naturally well-behaved, even prim, unless under Nina's influence, and until the turmoil in her family affects her. She has long, very fair hair, and an athletic bent -- in high school she participates in sports and shows a talent for dance. For much of the book she lives with her grandmother.
Her hero name is Hero, and she is assistant to Tan Coul. Her heroic ability is knowledge.
