These threads pop up every now and then. I've read some good books at the recommendation of forum readers.
Pillars of The Earth by Ken Follett - Thanks Slap.
Apocalypse Watch - Robert Ludlum - Thanks Alec.
Cold Mountain - Charles Frazier - Thanks Kekomutt (at the Freak)
I'm not a big Sci-Fi reader. The only memorable read in that genre was L. Ron Hubbard's Battlefield Earth. They tried to make a series but I didn't like the continuations.
As far as must reads:
Lonesome Dove - Larry McMurtry
The World According to Garp - John Irving
One Flew Over the Cuckoo's Nest - Ken Kesey
out of all the Stephen Kings I still like The Shining. (His last two books have been embarassingly bad.)
For something a bit offbeat and highly entertaining try Harlen Coben. Any of his titles that sound sports related. His main character is a Sports Agent - of sorts.
For those of you who enjoy satirical humor and cutting through the political correctness nonsense, try David Sedaris. Naked was great and I have his Me Talk Pretty Some Day waiting in the wings.
