To find out if there is an author with a similar name or if the name is indeed a pseudonym, you could:
* Search online book databases: Try searching for "E.A. Lempriene Knight" on websites like Goodreads, Amazon, or WorldCat.
* Check literary journals and magazines: See if any publications have articles or reviews about an author with that name.
* Contact a librarian: A librarian at your local library or a university library could help you search for information about the author.
It's also possible that you are thinking of a different author with a similar name. If you can remember any more details about the author or their works, that might help in the search.
