A house of secrets. A legacy of silence. A love that refuses to be denied.

When Viscount Quinton Hollingsworth returns to Sommer-by-the-Sea, everyone calls it a miracle—except Miss Mary-Ann Seaton. Once promised to him, she mourned him for three years. But the man who came home is no longer the one she loved. He’s secretive, distant, and clearly keeping something from her.

Mary-Ann has problems of her own. Her father’s shipping business is failing. Her new fiancé is not what he seems. And someone is watching her movements far too closely. With danger pressing in, she has no choice but to seek answers on her own—even if it means trusting the man who once broke her heart.

Quinton never intended to return to Mary-Ann’s life—or to fall for her all over again. But when his mission uncovers a conspiracy linked to her family, he’ll do anything to protect her. Even if she doesn’t want his help. Even if it costs him the one woman he’s never stopped loving.

As secrets surface and betrayal draws near, Mary-Ann and Quinton must decide whether love is a weakness… or their greatest strength.

A Vow for the Viscount is a heart-wrenching second chance romance with high emotional stakes, a fiercely capable heroine, a battle-scarred hero, and a promise that could mend everything—or break them forever.
