Just finished Ada, or Ardor.

If you want something with brilliant prose, multilingual puns on every page, occasional invasions of other styles, a distorted but familiar world, obsession-driven narrative balancing between passion and transcendence, it might be something for you - unless, like Martin Amis, you find it hysterical and yourself unable to ignore the dark reality of several characters, narrator included, having too much resources to care about morals or most laws.
