Tentatively scheduled for the fall of 2010, W.W. Norton will publish an anthology of Hint Fiction. What is Hint Fiction? It's a story of 25 words or less that suggests a larger, more complex story. The thesis of the anthology is to prove that a story 25 words or less can have as much impact as a story 2,500 words or longer. The anthology will include between 100 and 150 stories. We want your best work."
Submissions: August 1-31, 2009.
Pays: $25/story for World and Audio rights.
