 Isabel Allende says "of her female protagonist in Daughter of Fortune, Eliza, that she might well represent who the author might have been in another life."
 "Allende spent seven years of research on this, her fifth novel, which she says is a story of a young woman's search for self-knowledge."

 Allende also wrote a sequel to "Daughter of Fortune" entitled "Portrait in Sepia" which follows Eliza Sommers' granddaughter.

 Like the famous Arabic tales, these stories combine fantasy with biting social satire and psychological insight."
