Have a look at the list of 100 books on the first post here: http://funadvice.com/r/14v3kuda4dd
That is a list the BBC compiled of books everyone should read- there are a lot of classics on there and I agree with most that they included being worthy of a read.
The Bell Jar, Of Mice and Men and The Colour Purple are three that jumped out at me from there which I found particularly good. If you haven't read The Bell Jar, it is one of my favourite books ever, so I woudl definitely recommend that one as a start :)
there is also Frankenstein, Pride and Prejudice, Beowulf, Paradise Lost, and Cantebury Tales...etc etc...i would have put those on here the other day but my mind went blank
Oliver Twist - Charles ickens Moby ick - Herman Mellville. Anna Karenina - Leo Tolstoy. The Odyssey - Homer. The Giver - Lois Lowry. Speak - Laurie Halse Anderson.
oh i love oliver twist...herman mellville is a good writer but the book was awfully hard to follow and lengthy but good none the less. the odyssey was great 2 :)
1984 is a very very good book. easy to read and makes you think alot. a lot happens throughout the story so your never bored, and really good imagery
The Secret Garden definitely. Anne of Green Gables series, Emily of New Moon series, Little House on the Prairie series, anything by Dr Seuss.
The swiss family robinson, Pollyanna, the secret garden, white fang, call of the wild, and several others haha it would be an awful long list
For older readers (late teens ish and older) - anything by Asimov. Ayn Rand "Atlas Shrugged" Douglas Adams "A Prayer for Owen Meany"
Where The Red Fern Grows - Wilson Rawls Stargirl - Jerry Spinelli Lol it's been a long day, those are the only two in my mind.
Fahrenheit 451 ~amazing book of mice and men~ so sad and thats all i can think of that i liked

Lord of the Rings- Tolkien (The books are WAY better than the movies)
