Glad to see some are interested!
Can't really say much about the plot "yet", because I'd like to see where the potential to have it completed may be. If a writer around here is dedicated and talented then I'd give the plot idea to them, and if more than two writers are interested I'd happily release the story for community collaboration, OpenSource under
Benevolence Media.
For now, I can say what kind of a story it could be. A psychological thriller like Deathnote/Sherlock Holmes, fantasy/sci-fi elements akin to Inception/Life on Mars (John Simm)/Ghost In The Shell, maybe some Mobster themes like Baccano, Passion Pumping/Fate Breaking like Gurren Lagann/Springtime Of Youth(tm), and something philosophical in the midst.
The character can be either male or female, that's for the writer/community to decide. But the villains are many. It may even introduce various story-plotting concepts. Reader's Age-wise I'm thinking 15+.
