What is your favorite book/books?

[CGforever!]

1. Elminster: the making of a mage. Even if you don't like Elminster, I'd still give this book a try. Hell, even if you don't like Ed Greenwood, still give it a try, it's not like his other books. Easily my favorite book - it has pretty much everything you want out of fantasy fiction.

2. The Last Mythal series. Overall, this is probably my favorite series of books. It has its' flaws, but I go back and read through them every couple of years. Richard Baker understands elves better than any other writer I've ever seen.

3. A Deepness in the Sky. The best sci-fi I've ever read. If you've read A Fire upon the Deep, you might appreciate this one even more, but I hadn't when I read it the first time and still thought it was amazing.

4. Non-player. A single comic-book, the first (and so far, only) issue. Simply amazing. The best artwork I have ever seen in book form. A good read as well.

5. Wake. A french series of comic-books. Futuristic/alien setting, great artwork, serious and yet funny/occasionally lighthearted. Doesn't shy away from heavy stuff. Highly imaginative and creative. They stopped converting them to english, though.

I also love Homeland by R.A.Salvatore, Elfshadow by Elaine Cunningham, and Dissolution by Richard Lee Byers.

Hmmm...I can't really narrow it down to just a few books - especially not just one - but here's a list in no particular order.

The Lord of the Rings and The Hobbit, by JRR Tolkien - like a lot of other people here.
A Wizard of Earthsea, by Ursula LeGuin
A Wrinkle in Time, by Madeleine L'Engle
Eternity Road, by Jack McDevitt
Gulliver's Travels, by Jonathan Swift
Good Omens, by Neil Gaiman and Terry Pratchett - again, like a lot of people here.
Small Gods, and Wyrd Sisters, by Terry Prathett
A Hitchhiker's Guide to the Galaxy, by Douglas Adams
The Golden Compass, by Phillip Pullman
Sabriel, Lirael, and Abhorsen, by Garth Nix
Nine Princes in Amber, by Roger Zelazny
Macbeth and A Midsummer Night's Dream - these might not fit here because they're plays, but I'll list them anyway.
The Glass Menagerie, by Tennessee Williams - again, it's a play, so it might not fit here.

Sooo many, I could never pick even a top five, or ten.

However, since everyone seems to be mentioning Pratchett, I'll drop in that Night Watch is absolutely wonderful and probably my favourite of his, despite some stiff competition.

The Warlord Chronicles, by Bernard Cornwell, consisting of The Winter King, Enemy of God, and Excalibur. It's a fantastic historical take on the King Arthur myth (MUCH better than the ridiculous movies I've seen) and Cornwell is a master of characterization. Some characters won't look quite familiar (Lancelot's a real rotter), but each of them feels like a real person in their own way. It's also very different from the neo-Paganist interpretations that were made popular by The Mists of Avalon, depicting Arthur as an atheist whose concern is the here and now, and there are likable and unlikable characters on both sides of the Christian/Pagan conflict. A great and surprisingly quick read, it's gotten me interested in Cornwell's other, more historically grounded work.

All time favorite: Lord of the Rings by J.R.R. Tolkien

Very close seconds:
Chronicles of Amber by Zelazny
Silmarilion by Tolkien
Book of the New Sun series by Gene Wolfe (eerie, mysterious, melancholy, exciting, bizarre -- what's not to like ?)
Anything by William Shakespeare

Poetry:
Rudyard Kipling (Especially less celebrated ones like "Adam-Zad the Bear"
Thomas Macaulay (Lays of Ancient Rome)

Lighter Reading:
Various "Charlie Moon" mysteries by James D. Doss
Occasional forays into Jim Butcher

Well, that's probably more than enough for one post ...
