A Knight There Was (The Knights of England Series, Book 2) : A Medieval Romance

Following the return of the Black Death, Margery Watson nurses Golden Knight Matthew Hart back from his war wounds. A bond deepening between them, Matthew, who refuses to marry so his younger brother may inherit all, begs Margery to openly live with him. Margery agrees. Like her grandmother before her, she will risk all for love. But betrayal leaves Margery the wife of a wealthy goldsmith, who trades on her family name, ranked among England's oldest, while Margery and Matthew foolishly believe that time, distance and heartbreak will be enough to keep them forever apart.
