The Last PageAfterward by Amelia Williams.
Hello, old friend. And here we are, you and me, on the last page. By the time you read these words, Rory and I will be long gone. So know that we lived well, and were very happy. And above all else, know that we will love you always. Sometimes I do worry about you, though.I think once we're gone, you won't be coming back here for a while, and you might be alone, which you should never be. Don't be alone, Doctor. And do one more thing for me. There's a little girl waiting in a garden. She's going to wait a long while, so she's going to need a lot of hope. Go to her. Tell her a story. Tell her that if she's patient, the days are coming that she'll never forget. Tell her he'll go to sea and fight pirates. She'll fall in love with a man who'll wait 2,000 years to keep her safe. Tell her she'll give hope to the greatest painter who ever lived and save a whale in outer space. Tell her, this is the story of Amelia Pond. And this how it ends.
