umm... overall. Sometimes it seems like everything already been done! But I suppose it can't be avoided (either that or my friend and editor/beta is waaay to good at guessing twists)
One sci-fi story I wrote was called secrets can kill. IT was about teens who got pulled into a dangerous game full of puzzles set up by the villains of the story as they send monsters after them.
Actually, the only thing that wasn't stolen at the Louvre's Apollo Gallery is the Regent Diamond, figure no one would take it because something to do with a curse.
