Yes, but that's a pretty far-off version of Christian fiction. I have only read a few titles myself, but Christian fiction can be considered stories (of different types) that perhaps center around a religious theme, or concept, or person who believes (or comes to believe).
Just like in all fiction, there are good stories and there are bad ones. I can't speak for all of Christian fiction, but the ones I have read are pretty good.
I have read a lot of Ted Dekker's work. He writes spiritual and supernatural thrillers in the vein of Stephen King and Dean Koontz. I have also read a lot of Frank Peretti's work.
These books typically contain little offensive content such as swearing, sex, etc. (part of the fun some books, I know).
They tend to offer hopeful messages and most of them are not preachy books. If you've never read a Christian novel, take a look at some of these sites. I am not an expert, but I visit them on occasion.

I am sure that there are more (lots) of Christian authors out there besides these, but they are my two favorites Christian fiction authors (contemporary).
There's also a new book called Christ the Lord: Out of Egypt by Anne Rice that takes a look at what Christ's childhood might have been like. It's a great book and done very well (Anne Rice, of course!)
If you want more info, I can get you some emails for some people that know this Christian fiction stuff inside and out.
