Going on a very long train journey at Easter (2 days!) and need a long and good book - suggestions welcome. It has to not be too heavy (to carry, rather than read IYSWIM). Mostly I read non-fiction so any suggestions for that also welcome, history/politics/economics my particular thing but open to ideas . . .
ps, don't suggest a kindle, I don't travel often & don't want another bit of electronic 'stuff'
