The novel centers on the fortunes of two orphaned sisters, Ayala and Lucy Dormer. After their father's death, the sisters are taken in by two different branches of their family. Ayala, the younger and more imaginative sister, goes to live with her wealthy aunt and uncle, the Tringles, while Lucy is taken in by the more modest but kind-hearted Dosetts.Ayala's new life with the Tringles exposes her to the opulence of high society, but her romantic and idealistic nature causes friction with her materialistic relatives. She dreams of meeting an "angel" who will sweep her off her feet, a fantasy that keeps her from considering more practical suitors. Her refusal to conform to her aunt's expectations and her rejection of the wealthy but boorish Tom Tringle lead to her being sent away.Meanwhile, Lucy's life with the Dosetts is humble and filled with genuine affection. Her path crosses with Isadore Hamel, a talented artist who becomes a potential suitor. Lucy's practicality and grounded nature contrast sharply with Ayala's fanciful outlook.
