The Daughter of Voldemort
Hidden from the world for her entire life, Veronica Marvolo was slipped into Hogwarts at the age of 11 and has been keeping a low profile for the past 3 years. Bodyless and having only a seventh of a soul, Voldemort didn't exactly provide the white picket fence family life that many kids dream of. Nevertheless, He-Who-Must-Not-Be-Named wouldn't have his only child growing up in an orphanage as he did.
Voldemort could have made his return to power years before he did, but with the death of his child's mother, he used this time off to raise her to his standards and prepare her to be his right hand upon his throne. By the time she was 11, Veronica was skilled in magic way beyond her years and Voldemort could wait no longer to make his return to power. Although she needed no schooling, Voldemort had her slipped into Hogwarts with the intent to have her assistance in finishing off young Harry Potter while simultaneously freeing up his time to return to power.
Little did Voldemort know that young Veronica would be refusing to comply with her father's requests, starting with her pleading request to the sorting hat to be put as far from the Slytherin house as possible.
Three years later, Veronica has managed to blend seamlessly into the wizard community, trying to keep a low profile in the public while managing her father's threats when she refuses to act for his benefit. That is, until Potter needs her help and she must choose to sacrifice the only form of twisted family she has or let Harry's death be forever on her conscious.
(This is a fanfiction based on the Harry Potter series. I'm starting in the 4th book, The Goblet of Fire. My intention is to stay with the storyline of the series as much as possible while adding a whole other dimension concerning a new relationships between Harry and Voldemort's daughter. This will give a entirely different view of Voldemort while attempting to keep with the storyline of the original book.)
