It is; I recall it did incorporate the Medjugorje visions as part of its plot. The book itself is nonremarkable, mentioning them in connection with revising the Church.
Just curious, why is Medjugorje so controversial? What do the visions proclaim?
Are the visions on a level with seeing the Virgin on a tortilla and the like?
Just asking.
I've always thought them fairly credible -- I think the big issue that made many start to find them lacking credibility is that Mary allegedly said, in an apparition, that all religions were equally valid. I haven't been able to find any first-hand confirmation that the apparition actually included that message but I have to admit that I haven't looked all that hard, and I also would be suspect of any translation without knowing the typical use of the word in their native tongue.
Also there is an issue with fighting between the bishops and the Franciscans; most here believe the Franciscans are to blame, but I'm not so quick as I believe the original bishop, when the apparitions allegedly started, was a bit of a communist collaborator so I assume his opinions on the apparitions are suspect and he had a reason to not desire this to be true.
SO I guess I'm basically shrugging my shoulders at you...sorry not to have any better information.
