Favorite Fantasy/Sci-Fi novels
Here are a few in no particular order:

The Martian Chronicles by Ray Bradbury- Mankind explores mars and build settlements. Martians object. Very creepy.

Stormbringer by Michael Moorcock- The last and best book of the Elric saga. I was just going to say The Eternal Champions series by Michael Moorcock but that's over 100 books. This was my favorite. Moorcock writes in many different styles. The Elric saga is written very much in the pulp style, but Elric is not your typical pulp hero.

Caves of Steel by Isaac Asimov- This is the first of the robot series, a series of mysteries starring Elijah Bailey, an agoraphobic cop and R. Daneel Olivaw, a robot. R. Daneel was pretty obviously the template for Star Trek: The Next Generation's Data.

To Your Scattered Bodies Go by Phillip Jose Farmer- Every person who ever lived on earth is reborn on the banks of an endless river. This is the first book of the Riverworld series.

Vurt by Jeff Noon- Vurt is a feather, a drug and a portal to another world. It's a crazy world in there. Be careful. Be very, very careful.

Alice's Adventures in Wonderland by Lewis Carrol
