First off, if you've read DFW's Broom of the System, which yes, I did force myself to finish because I was in snowy Meeker, and really, there was nothing else to do, somebody, please explain it to me. I didn't get it at all.
But on the other hand, great book: Meg Wolitzer's The Wife. Too lazy to hyperlink today -- go look it up yourself. Perfect length for 2-hr flight from Denver to LA, and if you're a writer, it really does "the writing life" to a fantastic (by which I mean, totally imaginative to the extreme heights of possible career trajectory) and absorbing degree. I hate to fly, but the book kept me tuned in enough to not flip out entirely, and considering my general choice of flight reading is back issues of New York Mag and whatever tabloid has Jessica Simpson on the cover, that really is saying a lot. (Fair warning: if you're not, yourself, a wife, The Wife may not resonate as deeply for you ... don't say I didn't warn you. But for me, thought it was great, since I spend all my time thinking about issues like being a wife and/or writing. FYI, last year's I Don't Know How She Does It was similarly successful for me, so there you go.)
