This was making the rounds back in early June.  It may have been “an outgrowth of the Wiscon Periodic Table of Women in SF,” as someone put it when I glommed this from them. It strikes me as being rather light in the loafers for urban fantasy writers and I don’t believe paranormal romance is listed at all. So I’ve added some authors (in red) off the top of my head and the TBR pile (which means I’ve probably left out obvious examples—I didn’t want to make it a life’s work).  Not all of them are UF/PR. I haven’t listed male/female author teams (like the fabulous Ilona Andrews) since this list is supposed to be all about the females.  I welcome others to add to the list and pass it on if they feel like it.

The Rules of the Game Are:
Bold the women by whom you own books
Italicize those by whom you’ve read something of (short stories count).
*Star those you don’t recognize
Unmarked are those whose work you have not read
