The Duke and the Diamond
(2026)(The first book in the Paragon Heist series)
A novel by Ellie St. Clair
A stolen diamond.
A whispered accusation.
And a marriage that was never meant to end in love.
When the infamous Paragon Diamond vanishes during the Marquess of Eastclere’s spring soirée, Asher Fairborne, the Duke of Ravenscar, finds himself perilously close to scandal. Rigid, controlled, and determined to protect his family, his dukedom, and his heart at any cost, Asher knows there is only one way to silence society’s whispers—a swift marriage of convenience.
Lady Evelyn Stratford agrees for one reason alone: to protect her father’s name. Brilliant, benevolent, and unwilling to be ruined, she never expects her strategic marriage to the infuriating duke to ignite a dangerous attraction she cannot afford.
Forced into close quarters, Asher and Evelyn uncover secrets that point to a conspiracy far darker than a simple theft—and a traitor closer than either imagined. As suspicion tightens and desire flares, they must decide what truly threatens them most.
Because scandal can be survived.
But falling in love may cost them everything.
The Duke and the Diamond is the first book in a brand-new Regency romance series by Ellie St. Clair, featuring a marriage of convenience, grumpy versus sunshine tension, an alpha duke, and steamy romance.
Genre: Romantic Suspense
