That is a great idea, I am also a magician and a writer. I am only 14 but have already written a couple of novels, (Realistic fiction). I am thinking about writing about a teen magician and throughout the story the reader always guesses if the person has powers or if it is just slight of hand, since I can't say "Did a helix 180 cut and controlled the card to the top and then did a double lift…" That would make no sense to the reader and I can't be giving away stuff now can I. I think your idea is great and can have a lot of potential. My best advice for any writer is to know your characters well because they make the plot. I would love to read some of it when you get some chapters out. Pm me. I'll send you some of my stuff if you want.
I'm sorry did anyone else trip up on this at all?
Doesn't sound like a bad idea by the way, but then again it's not even a plot idea at the moment. A plot line and/or blurb could let us in a bit more.
Short story or a novel?
