from the back of the book:
The last priest is on the run. During an anti-clerical purge in one of the southern states of Mexico, he is hunted like a hare. Too human for heroism, too humble for martyrdom, the little worldly ´whisky priest´ is nevertheless impelled towards his squalid Calvary as much by his own compassion for humanity as by the efforts of his pursuers. A baleful vulture of doom hovers over this modern crucifixion story, but above the vulture soars an eagle - the inevitability of the Church´s triumph.
The Power and the Glory is one of Time's top 100 novels. Greene's comments on the book are here.
This is a powerful book -depressing and uplifting at the same time- and ultimately about redemption.
