About to leave her school, the Five Oaks Boarding School for Young Ladies, the beautiful but penniless Rosilda Harvey is told by her unsympathetic Guardian that she must take a junior teacher's job at the school and not come and live with her in the Lake District as she had hoped.
Very depressed at her uncertain future, she is unexpectedly offered a position by Sir Andrew Dexter, a handsome but autocratic official of the British Foreign Office, who suddenly appears unannounced at the school.
He wants Rosilda to act as chaperone and companion to one of her school friends, Princess Marianne of Montdeaves, as it is his mission to protect her from potential enemies.
The Princess is to return to her country high in the mountains in Central Europe immediately and in secret as her life is in danger from determined revolutionaries.
Rosilda, the Princess and Sir Andrew set off at once and, after a series of adventures, arrive in the Principality of Montdeaves, which is considered of vital importance to Great Britain and to future peace in Europe.
How Rosilda and Sir Andrew eventually manage to bring the headstrong young Princess to safety.
And what happens when they finally reach Montdeaves and meet the Ruler, Prince Franz, and a number of suspicious characters is all told in this exciting romance by BARBARA CARTLAND.
