The gunning down of her mother in a Richmond street sets young Helen Stockton Defoe on a journey of self-discovery. A physical feature she had first noticed when she was nine years old has made her feel apart and she has quietly capitalized on the privilege, never mind the aura, which surrounds her. She lives in her head and fills her thoughts - and days - with science, horses and art.

The more intently she begins to observe her remote, detached father, the more she learns about her place within the rarefied world she inhabits. Just when it appears she is at last becoming closer to him, it all falls apart as he coldly undermines her abiding passions, which causes her to question the identity she has created. Her rebellion leads her to Europe on a disturbing path dominated by chance and an evolving self-realization. As a result of these experiences she gains an ability to feel deeply, something from which she had always felt somehow excluded.
