Permuted Press has opened for novel submissions. They're looking for novels in the genres of horror, supernatural, and sci-fi of over 60,000 words. In the guidelines you'll find a breakdown of what's acceptable within those genres. On the FAQ page you'll find that they pay an advance against royalties. You can find the details here.
On that page you'll find an anthology call for "Fat Zombies" which I mentioned here a week or so ago.
