I only really read books on vacation. The rest of the time it's as much as I can do to keep up with our subscriptions to The Economist, The Atlantic and The New Yorker (no newspapers, thank goodness, even if The Economist calls itself one).
I just returned from a truly wonderful vacation in Canada - wonderful in many respects, the books being only one. I read The Omnivore's Dilemma by Michael Pollan, and the first half of JPod by Douglas Coupland.
The Omnivore's Dilemma is absolutely wonderful... well worth the read. I loved an early passage in which he reminds us that eating is, for most of us, our most pervasive engagement with nature, and that the depth of this engagement cannot be underestimated.
(More on JPod once I have finished it - I hope it does not have to wait until my next vacation!)
