Some easy reads.. links for reviews/summary.
The Ear, The Eye, and the Arm - Nancy Farmer
Redwall (and series) - Brian Jacques
Ender's Game (and an the subsequent series) - Orson Scott Card
Some not so easy reads...
Siddhartha - Hermann Hesse
The Stranger - Albert Camus
Candide - Voltaire
The Divine Comedy - Dante Alighieri This is where you will find the Inferno, the most famous of the 3 books. The other books are also excellent, so read the whole thing and not just the Inferno. This is also where you will find the famous quote
"Abandon all Hope, Ye who enter here" the most used translation...
My favorite Shakespeare (I'm one of the few, sad people I know who has read his complete works =/ )
The Tempest
Macbeth (where the Sound and Fury quote comes from)
As You Like It (my fav Shake comedy)
Really I would put more, but the more I think about it - the more exhausting it seems... some authors..
Hesse, Hemmingway, more Camus!, Tolstoy, Bradbury, ASIMOV (why haven't I seen him in the thread yet?) more Palahniuk, Tom Wolfe anyone? Please someone get some Vonnegut up here... Galapagos for the win. I'm tired. Any body a philosophy fan out there? Haven't seen any DesCartes, Rousseau, saw someone recommend Plato's Republic... that's not a fun read, imo. Interesting, but defintely not fun. Get Sartre's "No Exit" or Beckitt's "Waiting for Godot" these are plays, but freakin' awesome... UH, for a fun read someone grab some Neil Simon. Biloxi Blues GO.
Hell, if you want good Plato get something short... Allegory of the Cave is a fun read.
