I stumbled on this anthology from RuneWright Press and for a change this gives you several months to polish your submission, as it's not due until April next year. 'It Lives - Volume Two' is looking for horror, fantasy, paranormal, etc, about newborns, reborns and motherhood. Creepy, right?
[...] I want you do dredge up your most beautiful vision of a newborn or your worst nightmare. Volume One's stories had a high degree of emotion to them, and I want to carry that through into Volume Two. So do your best to take my emotions and run them through the ringer [sic]. I want to be exhausted by the time I'm done reading It Lives: Volume Two, and it's up to you to make sure I am. Motherhood isn’t outside the boundaries with It Lives either. Sometimes what gives birth can be just as delightful or horrific as what is born. Don’t hold back!
They're looking for 2,000 to 10,000 words, with a publication date of June, 2012.
There are other anthologies listed on their submissions page as well, so you'll have to scroll to the bottom to get to this one (but you might find something interesting on the journey). General submission guidelines for all their work can be found here. Remember to RtFGl when submitting!
Payment is a modest contributor's copy and $5-$10 via PayPal, but that's not unreasonable. Payment details can also be found on the guidelines page above.
