Actually, I was thinking of multiple starts, not just one.
So it could be
-
the teenaged Jon & Karyn in the existing "You Are What You Wish"
-
some group of college students ("Campus Mayhem"?), allowing scientific reseach & critical thought and at the mean time have wild parties and drunken fun-ness
-
an adult setting, eg. a mid-40s couple with kids of varying ages (e.g. 14, 12, 8)...
that's just the premise. Any kind of magic/science fiction could be in any story. The difference is how the agents react...
