Abra "Abby" Rafaella Stone is the daughter of David and Lucy Stone, the granddaughter of Jack Torrance and Sandy Reynolds, the niece of Danny Torrance, and the great-granddaughter of Concetta Reynolds.
Abra was born with very powerful psychic abilities, like her uncle Dan. Her abilities are even greater than Dan's were at his peak, to the point where she was able to generate a small earthquake with her mind. She physically meets Dan in her teenage years, though she begins psychically communicating with him almost from the moment she was born.
In the book, she has blue eyes and blond hair framing her face and spilling over her shoulders. Dan notes that she is "pretty, but not beautiful", except her wide-set eyes; he believes that she will be a heart-breaker in five years.
In the film adaptation, she has dark skin, long black hair and is a slim build.
