Sarah Ferguson, Duchess of York, has written her first novel for adults, to be released by the leading romantic fiction publisher Mills & Boon.

Her Heart for a Compass is based on the life of the duchess's great-great-aunt, Lady Margaret Montagu Douglas Scott.

She has previously written children's books, non-fiction about Queen Victoria, and her own memoirs.

She said: "I am proud to bring my personal brand of historical fiction to the publishing world."

"It all started with researching my ancestry. Digging into the history of the Montagu-Douglas Scotts, I first came across Lady Margaret, who intrigued me because she shared one of my given names," she added.

"But although her parents, the Duke and Duchess of Buccleuch, were close friends with Queen Victoria and Prince Albert, I was unable to discover much about my namesake's early life, and so was born the idea which became Her Heart for a Compass."

The story will include some real people and events and also draw on the duchess's own experiences but she said "my imagination took over".

"I have long held a passion for historical research and telling the stories of strong women in history through film and television," she added.
