She married to wealthy old men in their death bed to help her family. People called her "Lady Caregiver." She never hoped to be happy herself until...

Cornelia Rosenblatt, eighteen years old, was on her way to Duke Spencer's estate for her third marriage. Although she was a bride, she didn't look happy--she was being forced to marry this old man, almost dying, by her father for the third time. Her father, Baron Rosenblatt, made contract with rich noble men who wished to be cared by a young, beautiful wife. In return, he earned money to pay his debts. Cornelia cared for her first husband and second husband as earnestly as she could. They lived longer than anyone had expected...and people started to call her "Lady Caregiver." She had long since given up on the prospect of a happy marriage. This is a story of a young sweet girl who finds love and happiness at last.
