1809. Eliza Courtney and Haryo Cavendish lead opposite lives, blissfully unaware of the secret that binds them.

Haryo’ s life of luxury at Chatsworth House is shaken when pressure mounts on her to marry. A dreadful selection of suitors leaves her convinced that her late mother, the Duchess of Devonshire, was right: husbands are an incomparable nuisance.

As the season begins, all matchmaking – eager or reluctant – is interrupted by gossip over the ‘mysterious Eliza Courtney’. But will she and her friend Haryo make it through to the end of the season to discover just what makes her so?

Inspired by real people and events, The Secret Sister unravels the best-kept secrets of Chatsworth House.
