Upside Down

Astoria Carter was just a girl living a fairly normal life in England. Until everything changes. Everyone has disappeared; her family, her friends, the entire population of the human race, except for Astoria. And suddenly fictional characters were becoming real. At first, it may have seemed like the most wonderful thing in the world to Astoria, but as time passes Astoria learns that something evil is out there lurking behind all this, and aims to change the world forever. She teams up with The Doctor ( A 900 year old time-lord) and The Winchesters, to stop this evil before it reaches it's goal.
