I was recently asked to write a review of The Saint Gallen Mafia by Julia Meloni for the magazine Inside the Vatican. It documents the efforts of a group of theologically “progressive” cardinals to elect Pope Francis. The review is published in the January edition. You can access the issue here: https://issuu.com/store/code/S63QNZZH.
I recommend the work especially to those who have reservations about Pope Francis but have not followed his pontificate closely. But the book is helpful even to those, like myself, who have paid close attention to it.
