There are several interesting features, besides what, from the title, would seem obvious.
One of those is the narrative structure. Almost the entirety of the book was ostensibly dictated to a monk, who wrote everything that Jude of Doran said, in his presence, with goose quill pens, on parchment, in 1356 AD, in England. Jude was a peasant boy, perhaps 15 or 16 years old during the time of the narrative.
Another is the presence of Chinese characters in a book set in 14th century England. The author doesn't seem to know whether or not that really happened at that time, but it is a central feature of the book, in several ways, and certainly adds interest. One thing I can tell you, without giving away anything essential, is that footbinding, an ancient Chinese practice, plays an important role.
The third feature is that, perforce, a fair amount of the book, although not the main action, takes place in a monastery. Although monastery life is not seen through rose-colored glasses, Jordan presents it respectfully. She treats the death of a monk, and his promotion to God's presence, as if it were true.
Finally, the book is a love story, although Jude doesn't realize it until the end.
Here's a quotation that I found interesting:
"Ambrose always said that fear was faith in one's enemy . . . " Sherryl Jordan, The Hunting of the Last Dragon, New York: HarperCollins, 2002, p. 87. (Ambrose does not appear in the book.)
I see what Jordan is saying. In a sense, fear is faith in one's enemy, be it a dragon, or Satan, or tornadoes, or our own nature and appetites. But that's not the whole story. Christ told us that there are some things that we should fear:
Luke 12:4 “I tell you, my friends, do not fear those who kill the body, and after that have nothing more that they can do. 5 But I will warn you whom to fear: fear him who, after he has killed, has authority to cast into hell. Yes, I tell you, fear him! (ESV)
