All her life, Miss Gladys Bell was a wallflower whose parents despaired of her ever attracting a suitor. Then she met the man of her dreams, who said she was the woman of his. One passionate night later, Gladys awaits a marriage proposal that never comes. Reuben Medford, the ton’s most notorious rake, doesn’t even remember her name.
