I absolutely LOVE political thrillers.
Frederick Forsythe, Tom Clancy, Robert Ludlum and the likes are great.
A few days ago i ordered some classics on Amazon, will try some Victor Hugo, Jules Vernes and that kind of stuff. Also some japanese classics, i am sure you can get them in english, too. Try Natsume Soseki, Akutagawa Ryunosuke or Mishima Yukio.
Other than that, i mostly read non-fictional stuff on history, economy, politics, but i also like biographies.
A good one, funny to read is Anthony Bourdain's one, he's a famous cook. Great book, changes your views on retaurants forever!
