With her flaming red hair and emerald green eyes, Xenia's unusual beauty makes her stand out in any crowd – that is until she unexpectedly meets her long lost cousin, Johanna, amidst the wreckage of a railway accident.

Incredulous at finding her mirror image and desperate for a friend, Xenia's initial joy is soon replaced by misgivings when Johanna suggests an outrageous plan to swap lives for two weeks. However, these are soon swept aside by her forceful cousin and Xenia finds herself agreeing to help Johanna enjoy ten final days of freedom with the Englishman she loves before her arranged Royal marriage.

As her cousin steals away from the site of the train crash, Xenia suddenly realises all that impersonating Johanna, even for a short while, will entail. Especially as her cousin was travelling to meet and marry her fiancé, King István of Luthenia, and the journey must continue so suspicions are not aroused.

Surrounded by servants and diplomats, Xenia struggles to assume the Royal role that Johanna inhabits so easily and prays that her true identity will not be discovered.

Arriving in Luthenia, Xenia is instantly plunged into a world of political intrigue and drama a million miles away from the quiet life she previously enjoyed in the English countryside. With a Constitutional crisis threatening and rumours of revolution, Luthenia desperately needs this arranged wedding to go ahead to cement allegiances and maintain the balance of power in Europe.

As the Luthenian Court prepares for a grand State wedding and the nuptial date grows ever nearer, it seems that the beautiful cousins have only one desire in common – they both want to marry for love.

But who shall be their bridegrooms?
