On the Natural History of Destruction, by W. G. Sebald
Once you get hooked on W. G. Sebald's work it is hard not to regard most other literature as frivolous. He is, however, an acquired taste, like single-malt scotch. The first words of his complex and heavy prose are hard to swallow, but even if you have to grimace as the words go down, you will find that nothing else tastes quite the same. Moreover, if you read too many of his novels at a time, rich in language but deficient in plot, they may leave you a bit disoriented. They will also leave a very lasting impression.
