Is Kempowski's All for Nothing one of the great novels of the century?

After literally months waiting for a copy - only one exists in the entire state library system ! - I finally began reading Walter Kempowski's All for Nothing (2006), from the great NYRB series, a novel that all reviewers immediately recognized as a classic. And from the first 60 pp or so I am recognize that, at least at the start (and many novels of course start well but fall flat) this is a terrific book that should have received a lot more attention. Kempowski was apparently one of the greatest writers of post-war Germany, though he never attained anywhere near the worldwide recognition of others, such as Grass. He should have. This novel is set in 1945 in eastern Germany, and it focuses on a single household near the front and the Polish border; the family is of the upper echelon, descendants of what was once an aristocracy, then became a plutocracy; the family made money in investments in steel and rice flour, and the father is an officer in the German army, but far from the fighting, he is assigned to deal w/ acquisition of property to support the troops. Now that the war is near its end, he's in Italy seizing olive oil and wine; he keeps his family well supplied, at least compared with their less fortunate neighbors suffering from wartime shortages. So we are looking at an isolated home of privilege, in which the people - a wife, an "auntie," a 12-year-old son, 3 servants - live in complete naivete, without any recognition of the horrors inflicted by their government, nor the postwar calamities they will face when Germany falls to the allies. There's a generalized fear of the Russians, but without any sense that danger is imminent; they still think the German army will triumph somehow. The sense of a class in isolation and on edge is similar to that great European novel of the 20th century, The Leopard, and it also recalls a novel by Yourcenar, whose title I can't recall but is about a similar household at the end of the war (first world war, I think), living comfortably in a world soon to be destroyed. Kempowski composes the novel as a series of very short takes or segments brought together into groups - each chapter focusing on a different event of family member; but the narrator is always third-person, and we're always much more aware of the context than any of the characters could ever be - they are willfully obtuse or blind to evil, keeping their lives insulated and relatively comfortable. How can you blame them?, yet their oblivion is perhaps a higher form of evil. The narrative line is straightforward, and the individual scenes, at least so far, are memorable and distinct, several of which involve visitors seeking shelter for the night who are engaged in dubious actions, such as a man who claims to be a political economist who takes careful note of the house valuables - we assume he may later return w/ Russian troops who will appropriate the bounty. So far, a powerful novel that offers most Western readers a view of Germany at a time of great crisis, a view from inside, seldom before examined or appreciated.
