Russia
You can’t go wrong with Colin Thubron, and I’d put "In Siberia" at the top of the list. As one reviewer said about the region, these “are places that you would not wish to visit in your wildest dreams”. But one such place, Krasnoyarsk, was the destination of a group of British teachers (myself among them) on a British Council sponsored visit. On the flight to Moscow I seem to recall almost everyone in the group of eight sitting reading their Thubron and it provided us with a cultural and spiritual context for the trip that made the experience all the more profound.
