The Lost Duke of Wyndham - Avon Historical Romance S. Two Dukes of Wyndham, Book 1 edition

Jack Audley has been a highwayman.

A soldier. And he has always been a rogue. What he is not, and never wanted to be, is a peer of the realm, responsible for an ancient heritage and the livelihood of hundreds. But when he is recognized as the long-lost son of the House of Wyndham, his carefree life is over. And if his birth proves to be legitimate, then he will find himself with the one title he never wanted: Duke of Wyndham.

Grace Eversleigh has spent the last five years toiling as the companion to the dowager Duchess of Wyndham. It is a thankless job, with very little break from the routine . . . until Jack Audley lands in her life, all rakish smiles and debonair charm. He is not a man who takes no for an answer, and when she is in his arms, she's not a woman who wants to say no. But if he is the true duke, then he is the one man she can never have . . .
