Hi Meitou!
I am not sure I could even make a top ten but at the moment I am reading a book by Rebecca Solnit, who is an essayist, feminist, environmentalist and also Buddhist (she is talking at Upaya soon). In the book, which is a history of her awakening to injustice and her relative invisibility as a woman, she talks about seeing feminism as part of her bodhisattva vow.
Of novels, those which are explicitly Buddhist/Zen include:
Siddhartha by Herman Hesse (I tend to read this once a year)
A Tale for the Time Being by Ruth Ozeki who I believe is a Zen priest and her book talks of Dogen and Soto nuns.
Lincoln in the Bardo by George Saunders which won the UK Booker Prize in 2017 and talks about the Tibetan Buddhist bardo realms between incarnations, although I must admit to have not got around to reading it yet!
Someone also recently recommended a detective novel set in Tibet called
The Skull Mantra.
Out of Nowhere claims to be a Zen mystery set in San Francisco with the protagonist living at the Zen Center!
Thersa Matsuura is a friend of mine and has written several great collections of short stories based on Japanese folklore, many of which have a Buddhist element. Like Jundo, she is a long-time transplant from the US, having lived most of her adult life in Japan. Actually, I bet if I asked she would do a reading for us at Treeleaf!
Terry Pratchett's Discworld book on religion,
Small Gods, features The Order of Wen the Eternally Surprised, which is a sect rather resembling Buddhism (also given away by their other name 'the men in saffron')
Be interesting to see what other Buddhist fiction members have come across.
