Yes, Deb Manning is a published author -- seems to be doing fairly well for herself, too. Her pen name is "Debra Mullins" and a search on Amazon turned up five books -- and that's not counting her first book, which I own but which didn't show up on the list for some reason.
Here's what she says in her "About the Author" section:
I have wanted to be a writer ever since I was a girl, when I used to write stories about my favorite television show, starring my friends as supporting characters. Over the years, I dreamed of someday being published so I could share my stories with the world. Now that dream has come true.
I love to hear from readers. You can write to me at P.O. Box 381, Waldwick, NJ 07463
I met her once... nice woman
