ok. i think the first sentence is ambiguous; "reacting to the reaction to 9/11" could mean a number of things. so, people look at the next sentence, figure that's the subject of the paragraph, stop thinking there, and reply w/o reading the third sentence too closely.

so, whipping out my blue pencil, i'd say "What do you call books that are reacting to the fanatical devotion to the pope national security above all else that followed 9/11?" might get the answer you want.
