Probably Romans, Galatians, 1 Peter, or the gospel of John.
Of the gospels, Mark is probably my favorite by writing style, but John is my favorite based on content. And my family always read from Luke at Christmas and Easter, so Luke is kind of important to me, too.
John. I have a heard time really considering picking anything else.
Of the epistles I'd have to pick either one of the Johns or Peter but all of them are too short to really make the cut as my favorite. Of the Pauline epistles, I like Hebrews the best.
Most scholars agree that Paul probably didn't write Hebrews, based on the original Greek text. People (including most in my church) simply assume he did because it mentions Timothy.
