My favorite "theological thriller" is "A Skeleton In God's Closet" by Paul L. Meier. You get to see what might happen to the world if the Ressurection had not happened and you get to learn a lot about the technology and techniques of archaeology.
I'm reading his new book, "Beyond a Skeleton", but I'm not sure what to think of it yet.
I like very much Ted Dekker's book "When Heaven Weeps".
Mind you, I'm calling these Christian Fiction, because they are fiction written by christians. They certainly can't compare to Bunyan's works.
