From Ann Kjellberg, editor  Welcome to the holiday shopping season, Book Post readers! I hope at least some of you are spending your day off on the sofa with a book. Experts have shown (not really) that it’s the best way to metabolize the soporific effects of tryptophan. For our part we’ve been reading Brad Stone’s The Everything Store: Jeff Bezos and the Age of Amazon, in order better to understand the moment, but more on that later. Chances are some of you have trekked back to places you are from, or places your relatives are from, and are knocking about, perhaps readying yourselves for a break from the family.
