Hmm...I'd have to say at the moment, my favorites books/series/authors would be:
The Sword of Truth Series (Terry Goodkind)
The Hitchhiker's Series (Douglas Adams)
Fahrenheit 451 (Bradbury)
The Taming of the Shrew (Shakespeare)
One Flew Over the Cuckoo's Nest (Ken Kesey)
All Quiet on the Western Front (Remarque)
Think that about covers it for the moment, though there honestly have been very few books that I've ever finished reading and disliked. Dr. Jekyll and Mr. Hyde, The Three Muskateers, Watership Down (fluffy rabbits that kill each other, woohoo!), Purgatorio, and lots of others were all great. Yes I'm a dork, but reading is enjoyable damnit!=)
