Thanks to Alyson Hilbourne for letting me know about this competition from Dark Regions.
They're looking for stories about 'a sole survivor stranded on a deserted island'. The word count is from 10 to 1,000 words (yes, that's between ten and one thousand words). The best five stories will be published and gain a cash prize. First place wins $500 and it's free to enter.
You can write ten words, can't you?
