CORRECTED UPDATED POST…
This morning Samhain Publishing sent out a tweet asking for general cyberpunk and steampunk romance submissions, hinting that there would be an open call for anthology submissions in the future. Rather than one anthology, I’ve just learned that there will be two, one each for steampunk and cyberpunk.
Sasha Knight, Senior Editor at Samhain, hopes to have the new guidelines up soon, those for the steampunk anthology posted first, with cyberpunk to follow.
In the meantime, check out the publisher’s submission guidelines page for the skinny on their Angels and Demons, and Red Hot Fairy Tale anthologies.

Woot! I just blogged about this as well. Great news!
I know! Just wished I could figure out how to write in either subgenre . I’m strictly a fantasy/paranormal writer. Will enjoy reading them, however!
