* The name is misspelled. Are you sure you have the correct spelling?
* The author is less known. Perhaps they write in a niche genre or under a different name.

To help me find the author, could you provide more context? For example:

* Do you have any other information about them, like their nationality or approximate time period?
With more information, I can try to find out if this author exists and what they have written.
