We might not see each other very often during the year but my friend Barbara and I always make it a point to go in to the Boston Book Festival together. Our kids are in the same grade in high school and Barbara and I share a love of books so the train ride in and back is a chance for us to reconnect, complain about the kids, and talk books. This year, Hurricane Sandy was a blot on the horizon but the day of the festival was a crisp fall day in Boston.
