Still under the guise of her sister, Rosabelle, Annabelle finds herself falling ever deeper for Giles Stanton's charms. Giles has mistakenly convinced himself that Rosabelle is an unfaithful woman merely after the prestigious family's fortune, making Annabelle the target of his irritation. In the middle of this great misunderstanding, while at a party, a mysterious man calls out to "Rosabelle" by name; at the same time, Giles reunites with the source of his distrust of women-his very own stepmother... The nineteenth century English romance of switched twins reaches its conclusion.
