One writer that comes to mind that uses pseudonyms is Nora Roberts. She was actually born Eleanor Marie Robertson. She uses the Nora Roberts name for her romances. She uses J.D. Robb for her suspense stuff. She’s also written under Jill March and in the UK she writes under Sarah Hardesty.
A pseudonym can keep you private life separate from your writing life or whatever it is you are using a pseudonym for.
Personally, I don’t plan on using a pseudonym. However, I’m not sure yet what I will publish my books under whether it should just be Kristena Tunstall or should I add my maiden name and call myself Kristena Patton Tunstall. More than likely I will just go with the first but it’s kind of fun picking out the name you actually want to use when you go to publish a book.
So how about you. Do you plan to use your legal name or a pseudonym?
