I love this post. Thanks for making me smile.
There were Nine Kings in The Lord of the Rings... but I guess it doesn't count if its not in the title. LOL
Half (0.5) A King by Joe Abercrombie
That "11" looks a lot more like "II" to me. I haven't read it, or even the description, so there's no telling whether I'm right, but that would leave a hole for "11 Kings" and could also lead to a post about books with Roman numerals in the title (which might or might not refer to sequence in a series). Because why not?
