harry potter and sirius black fanfic

“You will hear many of his Death Eaters claiming that they are in his confidence, that they alone are close to him, even understand him. They are deluded. Lord Voldemort has never had a friend, nor do I believe that he has ever wanted one,” Dumbledore told Harry Potter with absolute certainty. But what if Voldemort did have a friend? Not just a friend but the friend? A millennia-old wizard, who learned the secret of Hogwarts from the great Four founders, and had his own goals to take over the world? To stop that ancient wizard, an ancient power is called upon . . . in the form of a girl. A Muggle-born at that. Christina Norton has powers beyond anyone's imagination but she is too caught up in the Chosen One Harry Potter's life and catastrophes. But as she starts to uncover the plans of Voldemort, she realizes someone else is working with him. Someone who wants her dead. Why? She doesn't know. She just knows she has to save her loved ones and Hogwarts from Malgino and for that she is ready to go to the end of the world. And fight whoever comes in her way. Warning: It was my first book, so the first volume is going to be a bumpy ride. Things start to change at the end of the second volume, so if you can hang in there till then, welcome. Disclaimer: I neither own the original Harry Potter book series (I mean y'all already know that but still) nor the book cover (I guess I edited it but it doesn't count).
