Novelist Dean Koontz is a Catholic who converted when he was in college. I had no idea, but it figures. (Incidentally, a companion article mentions his unlikely friendship with bio-ethicist Wesley Smith, who, until he corrected the piece on his blog, I always assumed was Catholic).
Speaking of the genre, Stephen King is not a Catholic. It's not up on their website yet, but the February issue of First Things has an outstanding essay by Ross Douthat on the God of King's novels. As a former King fan (I started reading him in 4th grade, which honestly explains some s*** about me), I found the article dead on and a great read.
