The Next Best Book Club discussion

I would love to hear what your favourite book of all time is

Given the scope of the question, I can unequivocally state that, since the past is finite and known by measuring from the point of the Big Bang, and that the future is infinite, that my favorite book "of all time" has yet to be written.

So far it's a revolving door of about 5- A Prayer for Owen Meany, Dune, Hyperion, Lonesome Dove, and Colony. That's not counting childhood favourites like Anne of Green Gables and Little Women, which I'll probably never stop reading. I think that some of my recently read books will probably make the list, but that will take a few more re-reads :-)
