:Not to be confused with the unpublished book of the same name by John Smith.
During the launch of the book, Newman had a book signing at a bookstore. The Tenth Doctor, nearing the end of his life, got his copy of the book signed. The two shared a poignant moment in which he was curious whether her great-grandmother's life had turned out well, and she wondered whether he was happy. (TV: The End of Time)
