Okay, so I know this isn't exactly how the story goes, but I thought up this AU where Harry has a sister that everyone knows about but they don't know who it is. Hope you enjoy!

In this story, you insert yourself, but you're a Time Lord not a human...This isn't based off of any of the episodes of Doctor Who just an idea I came up with in my head... Some of the storyline changes though... Time Lord you runs into a young man named Zak, starts adventuring with him, then you run into The Doctor... I'll try to update at least once a week!
