The Count of Monte Cristo, by A. Dumas
The art of love, by Erich Fromm
whew… that’s hard, so many good books.
I have a soft spot for Mervyn Peake’s Gormenghast trilogy though, it never pales with rereading
So should I stop picturing you as Meatloaf and start picturing you as Caramon? 
Not sure that I can pick a favorite – but Douglas Adams’ Hitchhikers Guide series certainly comes to mind as something I can read (and have read) again and again.
Archergal, I almost agree with you on The Last Unicorn, but it’s edged out by W. O. Mitchell’s Who has Seen the Wind, about growing up in a small prairie town. (Maybe partly because it’s set in Weyburn, Saskatchewan, my home town (even if he did call it “Crocus” in the book).)
BTW, since you and Auntie Pam both mention Bridge of Birds (which I’ll have to track down), you might like Ernest Bramah’s Kai Lung books; you can download the earlier ones at www.gutenberg.org and try to find the last, Kai Lung Unrolls his Mat, in hard copy.
A few of the better ones that come to mind:
Literary:
The Remains of the Day, by Kazuo Ishiguro
Atonement, by Ian McEwan
100 Years of Solitude, by Gabriel Garcia Marquez
The House of the Spirits, by Isabel Allende (and just about anything else of hers)
Martin Dressler, by Stephen Milhauser
The Magus, by John Fowles (a solid and confusing read)
SF/F:
The Sarantine Mosaic, by Guy Gavriel Kay (2 books)
The Book of the New Sun, by Gene Wolfe (4 books originally)
The Riftwar Saga, by Raymond Feist (3 books in the original series)
Hyperion, by Dan Simmons
His Dark Materials, by Philip Pullman (3 books)
Stardust, by Neil Gaiman (more fairy tale than fantasy). Also Neverwhere.
Historical:
Ramses, by Christian Jacq (5 books)
Alexander, by Manfredi (3 books)
The Wanderers, by Caiseal Mor (3 books)
And of course there are heaps more great books.
Ahem ::Puffs out chest::
The ladies already think of me as Caramon:D
No, no, not from the first of the twin novels, where Caramon is out of shape…Oh boogers…I’m still lumped in with fat mental images… 
I don’t do favourite, but then again, there’s just something about The Catcher in the Rye by JD Salinger. I love it. I goddamn love it.
I could never pick just one.
A Tree Grows In Brooklyn, By Betty Smith
To Kill A Mockingbird, by Harper Lee
A Fine Balance, by Rohinton Mistry
The Poisonwood Bible, by Barbara Kingsolver
Pillars Of The Earth, by Ken Follett
I love that book.
I have different favorites, depending on what I’m looking for in a read.
The Ordinary Princess by M. M. Kaye is definitely one of my favorites - it just makes me grin to read it.
My favorite as of late, “A Heartbreaking Work of Staggering Genius” and I’ll be damned if I can remember the author’s name. But he’s a kid, and it’s his first attempt at writing, and it’s simply great.
The Gypsy’s Curse Harry Crews
Far From the Madding Crowd Thomas Hardy
Dave Eggers.
Small Gods — by Terry Pratchett
Der Minus Mann – by Heinz Sobota (dont know if it got translated, though)
Winter’s Tale, by Mark Helprin – a wonderful, magical book.
This is one of those books that people either love or hate, as evidenced by the Amazon.com reviewers, who tend to give it either 5 stars or just 1 or 2 stars.
Me, too. A Tree Grows In Brooklyn is my favorite book.
Okay, so to ease the restrictions a little more, you can post more than just one favorite book!
Keep it coming!
