* A literary work? If so, what kind? A novel, short story, poem, play? Do you remember the author's name, or any details about the story?
* A religious confession? This is a common practice in many religions, but there's no single author.
* A personal confession? If someone is confessing something to you, then the author is the person making the confession.
Once you give me more information, I can help you identify the author.
