Who is the author of white horse alih?

There's no author named "White Horse Ahih." It's possible you're referring to a book or piece of work with a similar title, or there might be a spelling error.

To help me identify the correct author, could you please provide me with more information? For example:

* The full title of the book or work: Is there a specific title, like "The White Horse" or "White Horse of Alih"?

* The genre: Is it fiction, non-fiction, poetry, etc.?

* Any other details: Do you remember the plot, characters, or a specific quote?

With more context, I can help you find the author you're looking for.
