Novels every Christian should consider reading

I previously blogged about my contribution–a review of Huckleberry Finn–to a blog series that Justin Taylor is running on “novels every Christian should consider reading.”  I urge you to read the whole series, which includes different Christians’ take on classic novels like Tom Jones, entertaining reads like Patrick O’Brian’s sea sagas, and finds that I, for one, hadn’t heard of but am now anxious to read, like Mark Helprin’s Soldier of the Great War.

And now I turn the topic over to you.  What do you think are some novels every Christian should consider reading?
