I think this may be the nearest thing to a perrfect novel. It's set in Sicily around the time of the '100 days' - the beginning of Garibaldi's campaign to unite Italy (and extend the franchise along the way). The central character is an aging aristocrat. He is at once admirable, contemptible and pitiable. He is more aware than his peers that the power of his class is crumbling, along with his own previously formidable powers. His loyalty - to his family, his class, and a king whom he personally despises - dominates his actions, even while he knows the inevitability of failure. Yet his personal relations with his family are distant.
The book is a great work of art. Much is understated, implied, ambiguous. The revolution has bittersweet consequences: it is obvious what was gained, but something was lost (the author was also a count). So much is said in so few words. Occasionally the peaks of human artistry inspire awe: how can a person do this? This is such a peak. Paragraphs, pages even, are perfect.
