Bounced from one begrudging relative to another their whole lives, orphaned identical twins Sophie and Mariah Carter have always relied on each other for love and support.

Both long to visit London for the summer-Sophie to see the Queen’s Great Exhibition and Mariah to study the world’s finest collection of paintings. But when their cantankerous aunt insists she only has the means to sponsor one of them, Sophie and Mariah hatch a clever scheme: They will travel to London together and take turns playing the part of Sophie.

At first the plan runs like clockwork. But as the sisters avoid getting caught by increasingly narrow margins and two handsome gentlemen-both of whom think they’re falling in love with the real Sophie Carter-enter the equation, they find they don’t have the situation quite as under control as they thought.
