It's possible that:
* The name is misspelled: Double-check the spelling of the author's name. Perhaps it's a similar name like "Yvette H. Dean" or "Yetive Dean."
* The author is less known: The author might be a new or less established writer.
* The author writes under a pseudonym: Some authors use pen names.
To help me find the author, could you please provide more context? For example:
* The genre of the book: Is it fiction, non-fiction, romance, etc.?
* The title of the book: Do you remember the title of the book you are looking for?
* Any other details: Any specific keywords or phrases from the book?
With more information, I might be able to help you find the author you're looking for.
