Here's a fun thing that I sincerely hope a few of my readers will try. There's a great site, www.storycasting.com. I was just reminded, via a Storycasting "tweet," that it was May 1, 2008 when I "cast the first cast" on the new site. (First author cast, really, but I couldn't resist saying "cast the first cast.") I was invited to participate, it sounded like fun, and I went out and cast the theoretical remake of Pay It Forward. (Don't get me started.)
Since then, I've cast some of the characters for a few of my other titles, so you can see how they look in "the movie in my mind."
Now I'm inviting you to give it a try. I think it would be great fun to see how these characters look in other people's minds. It doesn't have to be Pay It Forward. In fact, it doesn't have to be one of my books. But if it is, please come back and leave a comment, and say what you cast, so I can check it out, and others can compare their casts with yours.
After all, it's free, it's fun, and it's a game just for readers. What's not to like?
