Well, it would, like Hyper said, depend on what your taste in books is...
...but if you're just looking for good books (in my opinion) from random genres, then here ya go:
"A Child Called 'It'" by Dave Pelzer (Some kid surviving off of awful parents. Interesting to say the least)
"A Tale of Two Cities" by Charles Dickens (It was the best of times, it was the worst of times...)
"A Wrinkle in Time" by Madeleine L'Engle (Wow. This story is...interesting. Read it)
"Alice’s Adventures in Wonderland and Through the Looking Glass" by Lewis Carroll (You can't resist!)
"Animal Farm" by George Orwell (Animal Farm, Animal Farm, never through me though shalt come to harm)
"Brave New World" by Aldous Huxley (Similar to 1984)
"Dilbert", a comic strip by Scott Adams (Of course, why not?)
"Flatland" by I don't remember at the moment (Explanation of Dimensions)
"Flatterland" by Ian Stewart (Explanation of many mathematical, dimensional, and quantum theories, yet still entertaining)
"The Darwin Awards" by Wendy Northcutt (I must say, this is VERY funny)
"The Farside", a comic strip by Gary Larson (Very...interesting...comics)
"The Glass Bead Game (Magister Ludi)" by Herman Hesse (Just read the beginning, for it has an interesting game concept in mind)
"The Hitchhikers Guide to the Galaxy" by Douglas Adams (For you crazy people)
"The Screwtape Letters" by C.S. Lewis (Great Christian book)
The comic strip by Charles M. Schulz (Peanuts rule!)
Issac Asimov's, H.G. Well's, and Jules Verne's books (Just in case you're interested in Sci-Fi and that junk)
The Harry Potter series (Who hasn't read this? Well, unless you're crazily afraid of witchcraft and blah, blah, blah)
The Lord of the Rings Series by J.R.R. Tolkien (C'mon. Who hasn't heard of this?)
Various short stories by Franz Kafka (Bah. Hard to understand, but that's existentialism for ya

)
Various short stories by Ernest Hemingway (Stories full of many descriptions. A bit boring, but good)
Don't forget about all the Classics out there!Remember, though...no Newberry Award Winners!
Yeah, yeah. I know I had to underline them instead of quote them (Quoting is only used for the titles of poetry and such), but I'm too lazy too do that.
