Joanna is the timid twin, the one who would rather paint than go out. Henrietta is the brave one, the renowned beauty who was engaged at seventeen to a handsome and rich young man. But when Henrietta’s fiancé is suddenly killed in a cholera outbreak, the twins and their cousin Brook are sent back to England.
Joanna and Brook are now thrown together, and both wish they had enough money to marry. But when one ill-advised night leaves Joanna with child, she has no choice but run off to France. If Joanna pretends to be Henrietta, she can have the baby in secret. And if Henrietta plays her cards right, she might finally be able to marry well enough to raise all their fortunes. Only Brook, who would do anything not to lose Joanna, stands in their way.
