Great-Grandma Rules the Magic Academy

Magic professor Agatha dies saving her young son and is reborn seventy years later as an eighteen-year-old girl at Hogwarts. She discovers that the white-haired headmaster is her son, while the acting headmaster and a Quidditch star are her great-grandsons. Protecting the neglected Poppy, she disciplines her descendants, confronts favouritism, proves herself in protective magic, and brings her family back together.
