David Foster Wallace's Infinite Jest is not a relaxing read. It's distinctly put-downable, in the sense that its sheer manic energy renders this reader so frazzled after twenty minutes or so that it has to be put to one side - only to inevitably be picked up as soon as recovery is effected.
Epic in its obsessiveness, mania, expansiveness, and dedication to exploring all forms of addiction and excess it represents everything we love and hate about modernity and America.
And since I've only just got started on it, it looks like I'm in for quite a trip. A big book in every way.
