What is your favorite sci-fi book?

Answer 1

There are so many to chose from, but I'll pick Ringworld by Larry Niven

Other Candidates are :

Foundation trilogy by Isaac Asimov
Cities in flight by James Blish
Rendez vous with Rama - by Arthur C. Clarke
The Moon is a Harsh Mistress - by Robert Heinlein
The Martian Chronicles - by Ray Bradbury
Do Androids dream of electric sheep? - Philip K .Dick

Answer 2

Currently I'm reading Philip Jose Farmer's "Riverworld" series. "To Your Scattered Bodies Go" and "The Fabulous Riverboat" were great reads.
Possibly the BEST Sci-fi piece I've ever read, however, is Harry Turtledove's "Guns of the South" - an awesome bit of alternate history wherein racist time travelers supply the Confederacy with modern weaponry, thus changing the course of the War Between the States.
Utterly fascinating on various levels, from the political intrigue to the foot soldier in the field.

Stranger In A Strange Land

If you're including fantasy,I'd say Something Wicked This Way Comes - Ray Bradbury, & The Dark Tower series - Stephen King
