Re: Recommend a book!
The Dune series. Start with Dune though and avoid any of the prequels or "Paul of Dune" until after you have read "Chapter House Dune", the final one in the original series.
The Dresden series of books by Jim Butcher, starting with "Storm Front". The short lived TV show didn't live up to the books, so if you've seen that, don't judge the books by it.
Codex Alera, starting with "The Furies of Calderon", by the same author of the Dresden series.
Sten, another series of books written by Chris Bunch and Allan Cole.
Straying a bit into the current weepy world of pretty boy vampires filled with angst and lusting after the hot chick, you could try the Blood Series by Tanya Huff, starting with "Blood Price". I was pleasantly surprised to find them readable after a friend recommended them.
If none of them fit the bill, you could try the masters of Fantasy, Raymond E Feist, David Gemmell, Terry Brooks, David Eddings ("The Redemption of Althalus" is my favourite Eddings book and it's a stand alone. One complete story, no follow ups or prequels).
