Very generic, nothing as fancy as the billionaires here reading Plato or Freud.
1. David Gemmell's Troy series. Even as a skeptical and jaded 30 something guy, that books made me want to be a hero, grab a sword and roar into battle. The fucking guy rewrote The Iliad! Nobody can ever write Odysseus like Gemmell. Ever. That is THE benchmark of that specific story and era. Even when I watch Troy (the Brad Pitt movie) can I find those characters believable as Gemmell rendered them so masterfully.
2. Conn Iggulden's Emperor series. Think it's 5 books but I done them all in 2 weeks.
3. Imperium and Lustrum by Robert Harris. Part of the same 'Cicero' books. A series based on the life of Marcus Tullius Cicero, the great Roman speaker. The last book in the series 'Dictator' comes out this year.
4. Millennium series by Stieg Larsson. It is pretty good, but haven't read it since nor do I want to.
5. Long walk to Freedom - Nelson Mandela
6. A Short History Of Nearly Everything - Bill Bryson
7. Shantaram - Greg Roberts. Very generic but gave me hope for my own life :p
8. The Hunderd Year Old Man Who Climbed Out Of The Window And Disappeared. Truly LOL stuff
9. All John Grisham's books.
10. The Road Home - Rose Tremain. The imagery in that book. The way she describes London in these times. Every paragraph is just perfect. The words are just a guide to rendering the own story in your head. It gently nudges you to create your own images.
