The Queen of Hearts by Barbara Cartland

Zelie and Sola are identical twins. Impossibly beautiful and impossible to tell apart, but only to the eye. Because, while the 'word on the street' is that spoilt, fickle and flirtatious Zelie is a little devil and they say that demure and thoughtful Sola is an angel by comparison. Zelie dreams of marrying a King and the riches that will bring. But Sola only craves the pure and enduring love her mother and father found and always treasured. Just when Zelie's dream comes true, Fate steps in and forces Sola to take her sister's place, at first reluctantly and then wholeheartedly marrying the King of Arramia to save his people from Revolution and bloodshed. But how can Sola ever be happy finding love at such a cost to her twin and under false pretences until death do they part?
