Hi guys, I'm going to get into books very soon I'd like you to suggest some key english litterature that not only I should know and have read, but second most importantly that is fun and whitty.

I've chosen The Catcher in the Rye as my first book and will start reading it today.

Please suggest this poor french canadian some good english pieces and tell me why I should read it.

Thanks in advance,

happyD

The Hitchhiker's Guide to the Galaxy seems to meet your criteria. It is a hugely influential work of fiction and also very fun and witty.

I tried ibooks and they wanted me to pay 28$ for the catcher in the rye. It's outrageous.

If you want fun and witty I would go for discworld novels. Guards! Guards! and Men at Arms had me laughing tears. I'm currently at Feet of Clay myself and I think those books are really good to get someone into reading.
As for important english literature I would recommend the usual suspects: Frankenstein, Dracula and Moby Dick left a lasting impression on me. Pillars of the Earth by Ken Follett was really good too.

Terry Pratchett is a god, it is such a shame that he has Alzheimer's disease. His books are really funny and imaginative, I love his characters, especially Death.

George Orwell's Nineteen Eighty-Four

I consider this novel so important for a young person to understand, I read the entire thing out loud to my dyslexic teenage son a few years ago. Orwell had a unique understanding of the political future planned for the world by powers we're not supposed to know about. He put this picture together in his horrifying novel about a society gone mad with control. The characters want to live normal lives, but are prevented at every turn by "Big Brother" - the eye of the government.

Orwell also wrote Animal Farm - a much shorter novel about how power corrupts. The characters are all animals - a strange thing in a novel intended for adults. I consider both his books to be VITAL reading for informed citizens.

i would recommend both, Swastika Night and Nineteen Eighty-Four, for comparison. Both are very interesting in their own way, even though they have pretty much the same plot.

i would also recommend you correct the word "Literature" in the title

Pride and Prejudice by Jane Austen.
Nineteen Eighty-Four and Animal Farm by George Orwell.
The Old Man and the Sea by Ernest Hemmingway
Frankenstein By Mary Shelley
Hamlet, Julius Caesar and other plays by William Shakespeare
Heart of Darkness By Josef Conrad.
The Outsider/L'Estrange by Albert Camus.
Oliver Twist and Great Expectations by Charles Dickens
The Importance of Being Earnest by Oscar Wilde

Beowulf is pretty good.
