I second the Song of Fire and Ice books. I LOVE them and I'm not much for fantasy reading. If you do like fantasy, also check out the "Drizzt Do'urden books. Those are entertaining. The first 3 or 4 are my favs, but all are decent.
but Tritones, I know David Copperfield is a "classic", but I just did not like it. I actually preferred Great Expectations for a good Dickens book. That being said, I freakin worship Dumas and Sir Arthur Conan Doyle. Read The Count of Monte Cristo and the 3 Musketeers series. For Sir A.C Doyle, read all the Sherlock Holmes books.
Taming of the Shrew and the Merchant of Venice are my fav Shakespeare books. 1776 by David McCullough is a great non-fiction account of the year 1776.
One of my favorite fiction books "The Descent" by Jeff Long. Its a mix of "Journey to the Center of the Earth" and an explanation of our "demons" that a lot of religions have. Everytime I read it, I get something new out of it.
For action/adventure, check out Clive Cusseler's older books. All his older Dirk Pitt stuff is great. The new crap he churns out is not so good.
For a good detective novel, I love Robert B. Parker's series. All his books were great. He even wrote a couple of westerns that were decent.
I hope this helps you out.
