Carina Press has put out a submission call for a rather interesting holiday theme. They are looking for novellas between 18,000 and 35,000 words in the Steampunk genre and with a winter theme. The stories do not have to be romances, and they can have absolutely any heat level. The deadline is May 15th, so get scribbling.
You can find out more here: Steampunk Submissions Call.
PS: If you're not quite sure what Steampunk is, Wikipedia has this interesting article, or you can sample some of the genre from Carina's store.
