Twelfth Planet Press is looking for novelettes for its doubles series. Stories should be between 10,000 and 20,000 words, science fiction or fantasy ("speculative fiction"), and they "are particularly looking for works that feel fresh, different and take risks to push boundaries and ideas".
Submissions will be open from 1 December 2009 to 28 February 2010, and should be sent as RTF attachments to email@example.com. Payment is $100 advance and 8% royalty on subsequent print runs.
