After her quiet life in the highlands of Scotland, the laird's daughter Ola McNewton is looking forward to going to London to take part in Queen Victoria's jubilee.

At first it seems a good joke to pretend to be a Balkan princess and be entertained by the handsome Duke of Camborne. During one enchanted evening together, they fall in love. But did the duke fall in love with her or with the mysterious Balkan princess?

Then the security services, fearful of a plot on the queen's life, become suspicious of Ola, and it seems that only the duke can save her. How they overcome the obstacles and realize their true love for each other is revealed in this exciting and romantic novel by Barbara Cartland.
