Anastasia Granger is the older sister of Hermione.
The day she received her letter to Hogwarts was when everything changed. She had started studying magic and learned everything she could, and that included memory charms.
The day she would be going to Hogwarts was the day she obliviated her muggle parents and her three-year-old sister, of her existence.
Anastasia knew that there was no turning back once she obliviated them. She would go to Hogwarts without her family remembering who she was, and she would be known as a half-blood instead of a muggle born.
At Hogwarts, Anastasia becomes a new person. She is not only unbelievably intelligent but extremely powerful. This leads her to become dangerous, and maybe even a threat to the wizarding world.
Things start to happen at Hogwarts and Anastasia is the one to take the blame. Will she get expelled, go to Azkaban, or even get killed? Maybe those three in order.
Her adventure is one of sorrow, tragedy, love, revenge, and evil. She will be faced with challenges. What will happen when there comes a time when she has to choose a side?
It's up to her to choose the good side with her friends and family or the dark side with her true love and her fellow Death Eaters. It is her choice. One mistake and her whole life could be ruined forever.
