The first great novel of the 21st century uses the sinister beauty of the American Tax Code as a springboard from which to launch into a genuinely serious discussion of the origins and importance of civic responsibility amidst the hazy, blurred stupidity of a country in quick decline. Contrary to many reviews, I don’t think it’s about boredom, and it’s certainly not boring. Another posthumous editor-to-manuscript resuscitation, the book hangs heavy with the clotted spectre of Wallace’s suicide, which makes the writing glow all the more painfully through it.
