It's possible:
* There's a typo: Double-check the name.
* They use a pen name: Maybe they write under a different name.
* They're a relatively unknown author: It's possible they haven't been widely published.
To help you find the author, could you provide more information about their work:
* Genre: What type of books do they write (fiction, non-fiction, poetry, etc.)?
* Topics: What are their books about?
* Any specific titles you know: Even a partial title might help.
With more details, I can help you track down the author.
