If you want some light reading I would say anything by Tom Sharpe (humourous reading) not very stimulating but they are good books, one to make you think a bit more, is Addict, by steven smith, How he became hooked and got himself off of drugs, I could not put that book, down (might be a bit to heavy for holiday) but worth a read at some point., also have you read Angelas ashes, by Frank McCourt ? an unbelievably good book and that is inspiring more than stimulating. have great holiday
