Top three is tough, but I'll try to go with ones you might not have already heard about:
1. "Book of the Long Sun" by Gene Wolfe
2. "Paradise War" by Stephen R Lawhead
3. "The Dragonbone Chair" by Tad Williams
Stephen King maybe too obvious to list, but IMO every SciFi fantasy fan should check out:
1. TALISMAN - Time and dimensional traveling werewolves set
in both modern and medieval times. The book almost has it all but unfortunately no human Roombas were not included.
2. The Stand- already read it? No problem! This book gets better every time.
3. Dark Tower Series - I can't wait for the new book. But will the new Book 5 and cause the old books 5,6,& 7 to become 6, 7 & 8?
BTW- if you liked Terry Goodkind's Wizard's First Rule & Stone of Tears, but dropped the series because the third book of the Sword of Truth series sucked so bad (and it does suck), skip to "Faith of the Fallen" which many consider to be his master piece and then skip to the 3 Chainfire series books- which are all pretty fun once they get going (well, unless you hate climatic endings that have as much to do with violent Soccer death matches where severed heads can serve as the ball as they do with epic Battles).
