[Admin: this will need fandom tags]

First the song/filk rec:

Pretty Little Dead Girl was my introduction to the music of Seanan McGuire, now better known as one of the most prolific and versatile writers of fantasy and SF to debut this century - both the song and the (now-OP) original CD. Fortunately, there are more CDs, featuring a sizeable proportion of female-centric themes (see particularly Wicked Girls, although Seanan is popular enough that some of the CDs are also OP, and the Web page is not as current as it might be; you will need to poke at your favorite local filk dealer on that front nowadays, CDBaby having morphed away from the retail disc business.

From my own fic archives, meanwhile:

A Woman Is Entitled....
Galavant (Madalena & Gwynne) • AO3 / Gen / ~3500 words

The opening number seems clear enough: Madalena and Galavant were madly, hopelessly, genuinely in love. Yet the Madalena we meet at her wedding to Richard -- to say nothing of the woman she proves to be as the series progresses -- doesn't seem to have been in love with Galavant at all. Surely both these stories can't be true...

...but then again, this is a musical. And a fantasy, since there's an actual wizard in it. And that being the case, there just might be an explanation.

(Also, since this is a story set inside a musical, there is a song woven into it....)
