It's the best of the bunch, but it's saddled with a deeply unconvincing romance and it's clear the author still has no idea what to do with her women characters - where they exist (which is rare) they're the flattest portrayals possible. Also, there's a difference between an index and an appendix, and if an author is going to include four of the bloody things it might behoove her to cut that number by half by sticking the various names in a single index where they belong. 

When it comes to fantasy appendices Tolkien has a lot to answer for. As far as I'm concerned, if it's not interesting enough to make it into the text proper, keep it in the draft folder where it belongs.
