Summary
For the first seven years of her life, Michaela Stirling was raised as Michael Stirling, heir to the earldom of Kilmartin. She grew up riding, managing land, and learning the responsibilities of a future lord alongside boys who would inherit their own titles one day.
This is how she met Anthony, Benedict, and Colin Bridgerton.
But no one could have anticipated that Michael would become Michaela. Or that her inheritance would pass to her cousin John, and the life she had been so meticulously prepared for would be abruptly snatched away.
Years later, Francesca Bridgerton enters society as the season’s Diamond, expecting a quiet and sensible future.
What she does not expect is John Stirling’s thoughtful courtship. Or the return of his cousin Michaela, her brothers’ oldest friend, whose charm, confidence, and complete disregard for propriety have only grown more dangerous with age.
And by the time Francesca begins to understand Michaela Stirling, it is already far too late.
