The Duke's Directive

Heirs & Heroes: Book 4

Published Copy

Blurb

He chose her to save a legacy. She married him to survive. Neither planned on love.

Jane Lightwood has spent years making herself invisible. Quietly absorbing her father's cruelty so her sisters wouldn't have to and relegating herself to a life a spinsterhood. So when the Duke of Aylton appears in desperate need of a bride, she accepts his marriage of convenience not out of hope, but survival.

His Grace Richard Kenworth has no illusions about love. Betrayed by his first wife and up to his neck in familial treachery, he takes the hand of the only lady he dares trust. But to his shock, his quiet new bride systematically breaks down the walls protecting his heart.

After years of harsh words, Jane struggles to trust her heart and Richard. When the Duke's enemy moves against Jane, he discovers that protecting his dukedom means less to him than saving her.

Can two people wounded by the past build something real before a ruthless enemy and their own fears destroy it forever?

The Duke's Directive is the fourth book in Lorin Grace's Heirs & Heroes Regency romance series. If you love slow-burn romance with just kisses, brooding heroes who fall hard, and heroines who discover their own worth one careful breath at a time, this is the romance that earns every breathless moment.
