Angels & Demons (the novel is actually a prequel to DVC, but most likely will be filmed as a sequel) probably won't cause as much controversy as the last one, though it's themes and plot still revolve around religious issues. The Wikipedia site on the novel gives a basic intro:
The basic plot is a classic race against time to find a hidden bomb and hunt down a serial killer in Rome. As its backdrop, the book debates the question about which is to be trusted - science or religion. It purports to show how the Vatican works as the plot to blow it up is uncovered during the conclave, revealing hidden secrets and mysteries as the story unfolds.For more, go here.
