I've been reading Tolstoy, loving his characterization. One of the most "real" authors I've read. My favorite book of all time is Alice in wonderland because its just plain fun.
I'm into cyberpunk myself. William Gibson (Neuromancer), Neal Stephenson (Snow Crash), Walter Jon Williams (Hardwired), the classics. Also some good new stuff too; Paolo Bacigalupi (The Windup Girl), Richard K. Morgan (Thin Air & Altered Carbon). Lot of good stuff out there.
