Just saw on WGN TV a segment about house swapping, an innovative way to buy a home. You list your home online and swap it with someone who has a house you like. This outside-the-box concept seems to be catching on. I'd say you'd have to be careful if you tried this, but if done correctly, it could be a great opportunity.
What about people swapping? I've read a number of books where for some reason the main character swaps identities with another person and all sorts of mayhem results. Later comes the confrontation and confession. All seems lost, but then by some miracle the day is saved.
One famous swap identities book is The Prince and the Pauper by Mark Twain.
The original Parent Trap movie with Hayley Mills is a favorite of mine.
Do you know of any other books or movies where a person swap takes place? Or, maybe you've written one yourself. Please share.
