A Lasting Legacy (a harry potter fan story from a different perspective)

Kerri had a troubled start to her life after her father was taken away when she was three years old, now she lives for six weeks a year with a strange man, a man with a hooked nose and dark hair. But she has a purpose to her life, the lasting legacy her father left behind, to destroy the ones who took him away... the ones who shape the minds of millions: The Ministry of Magic.
But Kerri grows to realise that there is another side to this story a side she has never been told before, will she still keep her fathers legacy, or join those she once thought to be enemies?
