She was my pride—a wise and beautiful woman who had been expected to have a promising future as the eldest daughter of an earl's household. However, her engagement was broken off, and she became a commoner. Now I was told that such a sister was on her deathbed. I headed to the location mentioned in the letter to meet my sister.
