Perhaps I missed it, but I'm surprised I didn't see a book list yet!

If you wish, whole book series can count as one.

In no order, my top 5 favorite reads:

1) The Hitchhiker's Guide to the Galaxy series
2) His Dark Materials Trilogy
3) 1984
4) Harry Potter
5) Lord of the Flies

Here's mine, in no particular order and off the top of my head:

1) The Stand (Stephen King)
2) Dune (original only, the sequels get a little boring)
3) Slaughterhouse 5 (Kurt Vonnegut)
4) The Great and Secret Show and its sequel (Clive Barker)
5) Catcher in the Rye

Very honorable mention: Flatland
