It's possible:
* The name is misspelled: Double check the spelling and try searching again.
* The author uses a different name: Perhaps they publish under a pen name or have a different middle name.
* The author is relatively unknown: They may have self-published or published in a niche market.
To help you find the author, could you provide any more information, like:
* What kind of books do they write? (Genre, topics, etc.)
* Are there any other titles you know of?
* Is there any other information you have about them?
With more details, it might be easier to track down the author you're looking for.
