Falling in Parallels

A girl named Sophie- a Doctor Who fan in our world- is transported to Universe 7300126188883, or as we might know it, the Whoniverse. This is a spin on the classic "follow the script of Doctor Who with a new character in the mix" format; except the new character really, REALLY shakes things up in a big way, and must prevent a hostile takeover of reality itself. Part 1 of Parallels.
