Foster children find themselves between the desire for security, which can be provided by a foster family when their biological family is unavailable, and the wish to know their biological parents and maintain contact with them. The theme of the book is how foster children, biological parents, and foster families have navigated these two opposing orientations during the foster care relationship, what has become of these foster children in adulthood, the relationship dynamics they live in today, and the significance their biological and foster parents still hold for them.
