It's possible that:
* There is a misspelling in the name. Perhaps it's a different spelling, like "Amy Richards" or "Amy Richardson."
* The author is not widely known or published. There are many authors who publish independently or in smaller presses, and they might not have widespread recognition.
* This is a fictional character or a pseudonym. If you've come across this name in a fictional context, it's likely a fictional character.
To help me find the author you're looking for, could you please provide more information, such as:
* The genre of their writing: Is it fiction, non-fiction, poetry, etc.?
* Any specific titles or works you know of: Do you remember the title of a book or story they wrote?
* Where you encountered the name: Did you see it on a book cover, website, or elsewhere?
With more context, I might be able to track down the author you're looking for.
