The Artist (Doctor Who fanfic)

When the Doctor meets an old friend from Gallifrey, you can certainly say he is surprised. This crazy time lady knows a lot of things, and she knows the Doctor will be in danger in the future. She's trying to see if time can be re-written, but when a powerful enemy rises once more, things seem worse and worse. Can Corona, (aka the Artist) see if the Doctor can be saved from the enemy, even though they may not be able to save herself? Can she, the Doctor, Amy and Rory, Captain Jack Harkness, maybe River Song, and a bunch of other people to defend the certain evil that has risen one to many times? Read and find out!
