You know what else, before I forget: I recommend
"A Great Clerk of Necromancy", by Catherynne Valente.*
I'm not actually sure which Hugo category you'd vote for a poem in. Short story? Related work? Probably related work. I'll have to read the definitions. Or maybe prior winner lists, see if there's precedent.
* I mean, basically, I recommend everything by Valente; she has become one of the authors whose stuff I'm just going to buy right away and not even bother test-driving through the library anymore. Nonetheless! I especially liked this!
