To the Stars and Back {Doctor Who - 11th Doctor}

The Doctor is lonely, so very lonely. The gap which was made by the Ponds still hasn't been filled. Until one day, a town in London is under attack. There, he meets a bright young woman, Evanna Lockhart, her best friend Lana and her sort of boyfriend Matt. Together, he and Evanna take on the monsters and try to save the world. What will happen when she's asked by the Doctor to join him? Will she accept? Or will she decline after finally finding ground in her life?
