Faith and Fiction Saturday: Books Where the Main Character Rejects Faith

Faith and Fiction Saturday is a weekly discussion of the intersection of faith and fiction. Feel free to post on your own blog or join in the discussion in comments.

Amanda recently raised the question of why characters in today's general market books are without religion. She wanted to know why faith is either a huge deal to the storyline or completely absent. I thought this was interesting, and followed the discussion in comments. Jodie brought up that there's a lack of books where characters consider faith or religion but decide it against it for one reason or another.

I have to admit that really got me thinking. Can you think of any books in the general market where characters consider religion but reject it? I searched my brain and only came up with one book and it's not exactly the same thing.
The Big Love by Sarah Dunn is about a girl who grew up as an evangelical Christian but left the faith. It's significant to the storyline because it still affects her in many ways. But the book isn't really about how she made that choice, only that she did.

Another book where a character had an evangelical stint was Mrs. Perfect by Jane Porter. It seems the character in the book no longer practices the faith but had a time in her life when she did and she remembers it fondly in the novel. I remember appreciating it for the positive portrayal even though the character was no longer really practicing or active in a faith community.

I can think of one book in the Christian market where a character considers conversion to evangelical Christianity from Mormonism, but in the end chooses not to. Books about conversion might also be in short supply. (in general market fiction they are probably in fine supply in Christian fiction!)

So that's today's question for you. Rejecting faith is a part of the faith experience like embracing it so do you know of any books where the characters have considered faith and rejected it? How about books where characters convert from one religion to another or even from one form of Christianity to another?
