This biography reveals a fascinating and complex figure, one who creates and re-creates her fiction by drawing on life experiences. At various stages, McCaffrey has been a beautiful young girl who refused to fit into traditional gender roles in high school, a restless young mother who wanted to write, an American expatriate who became an Irish citizen, an animal lover who dreamed of fantasy worlds with perfect relationships between humans and beasts, and a wife trapped in an unhappy marriage just as the women's movement took hold.

Author Robin Roberts conducted interviews with McCaffrey, her children, friends, and colleagues, and used archival correspondence and contemporary reviews and criticism. The biography examines how McCaffrey's early interests in theater, Slavonic languages and literature, and British history, mythology, and culture all shaped her science fiction. The book is a nuanced portrait of a writer whose appeal extends well beyond readers of her chosen genre.
