Some people here have listed
The Old Man and the Sea, which is my favorite book of all time.
Several have listed LOTR, which is my
second favorite book of all time.
My, what interesting points of view people have in this place. I love MobileRead.
Anyway, IMO the most overhyped classic is
Alice in Wonderland. I thoroughly despise that book and the people who force-feed it to children convinced it's a "children's book". It couldn't be farther from one.
So I cannot begin to tell you how much I hated having to look at that damn book
every single god damn day while working on the early dev versions of Sigil since the epub version of Alice was the most advanced (layout-wise) epub I could find. Fortunately, zelda provided an astonishing
Three Men in a Boat epub and that's been my main benchmark for a while now.
