Authors Whose Last Names Begin With "X"

To be honest, I am a bit stymied for authors whose last names begin with "X," much less Christian authors. There's a list on Goodreads of books by authors whose last names begin with "X". I haven't read any of the books, so I can't personally recommend any of them. 

If you are interested in Ancient history, you might like books by Xenophon, such as The Art of Horsemanship, or The Persian Expedition.

Or there's Xue Xinran, a Chinese author, who writes Biographies & Memoirs, Literature & Fiction, History. Her books, The Good Women of China: Hidden Voices and Message from an Unknown Chinese Mother: Stories of Loss and Love look intriguing. 

There's also Meihong Xu, another Chinese author. Daughter of China: The True Story of Forbidden Love in Modern China looks like it might be an interesting read.

Can you recommend any other authors whose last names begin with "X"? Please share in the comments below.
