Van Dorn agent Isaac Bell knows that when the President of the United States asks you to undertake a special mission, the only appropriate answer is, “Right away, sir.” As an official observer, Bell is supposed to avoid action, but that’s like asking a fish to shun water. After battling in the trenches, he finds himself flying beside a group of Allied aviators, unwilling to let them fight alone, even when they are faced with capture. Bell and his compatriots are imprisoned in a medieval castle—one that’s withstood the test of time and countless assaults by conventional weapons in its history.

Kurt Austin and his crew are back to slake their thirst for action as they attempt to drown an eco-extortionist's plan to control the world's freshwater supply.

Who will become the next prime minister of Italy, and who will be the next pope.
