I wont say of all time that would be too hard. This year so far the best book Ive read was Storm Front by Jim Butcher.

Hands down, Water for Elephants

I would say A Thousand Splendid Suns by Khaleed Houseini.

I have Water for Elephants in my TBR pile and I have heard so much about it. I think I might read it next.

Definitely Eat, Pray, Love by Elizabeth Gilbert. 

I agree with Dawn...A Thousand Splendid Suns!!!

Water for Elephants - Sara Gruen and Harry Potter and the deathly hallows.

The Death and Life of Charlie St Cloud by Ben Sherwood

Mike, you are the first person I Know that read that book too!!! It was a cute book!!

Another vote for Water for Elephants

I read Snow Flower and Water for Elephants last year - and they were among my top 3 best books of the year!  This year, I'd have to say The Book Thief by Mark Zukas, followed closely by Harry Potter and the Deathly Hallows

That's a toughie. I looked back over my book journals and I think I'd have to say (since I can only pick one, you meanie!) SHANTARAM by Gregory David Roberts.

A Thousand Splendid Suns -  I couldn't put that book down!

Peony in Love by Lisa See

Since I'm a little behind on the bestsellers, I'd have to say "My Sister's Keeper" by Jodi Picoult and "Eat, Pray, Love" by Elizabeth Gilbert.

I'm not finished with it yet, but I think The Amazing Adventures of Kavalier & Clay might take that honor.  If not that one, then One Big Damn Puzzler.

 Probably "Animal Vegetable MIracle", and also a fairly obscure historical novel called "Refuge."

I've spent much of the summer re-reading a lot of older books; there doesn't seem to be much new out there that grabs me. Several of the others listed I read last year.....

I think mine would be Black for Remembrance by Carlene Thompson.  Very creepy and I loved it!

I'd say A child called it by Dave Pelzer, awfully hard to read because of its subject matter but brilliantly written.

The Thirteenth Tale

Ditto to everyone who said eat, pray, love by Elizabeth Gilbert.  It was the most astounding spiritual book (NOT a religious book) and is a definite keeper for me!

Archangel by Sharon Shinn, followed closely by Water for Elephants

I'm a little behind here, but the best book I read this year was Atonement by Ian McEwan.

I'd have to say A Thousand Splendid Suns or Devil in the White City.

Forever Lily: An Unexpected Mother's Journey to Adoption in China by Beth Nonte Russell was definitely my favorite this year so far.
