Alright, I voted for several, also for 'All men are mortal', which is an excellent book with several 'layers'. One can read it as an adventure, but also as a masterpiece of the existentialist philosopher Simone de Beauvoir.
I loaded several books on my ereader/iPad from MR/bought the Scarlet letter, Study in scarlet, The sheltering sky, The American senator and High wind in Jamaica and the collected works of Edith Wharton.....for I'm leaving tomorrow....travelling 24 days in Uzbekistan (Central Asia) and Xinjiang (China)...
..I don't know about wifi.
(plenty of time to read though, as I will be travelling on 4 different trains/busses/car over long distances)
