At last a decent thread is revived! Or reincarnated at least. Maybe a slightly bland list to some - but unless it's star wars (old republic) or swords and magic based I probably won't read it.
Already mentioned but simply the best fantasy author around, Steven Erikson... Seriously, people need to have read mbotf, (As well as Ian Cameron Esslemont's contributions).
Brandon Sanderson, who as most that care will know is finishing up WoT, his Mistborn Trilogy is brilliant though
The Black Magician trilogy by Trudi Canavan, as well as it's prequel book and sequel series (I've heard good things about her Age of Five series too).
Scott Lynch, Over Christmas I read: The Lies of Locke Lamora + Red Seas Under Red Skies. Meant to be a 7 part series but he has 'issues', so we'll see. Shame if more don't come out though. Medieval type setting + con artists.
Brent Weeks' Night Angel trilogy, two thumbs up. Have not had the time for black prism yet.
Nathan Fillion fans should get hold of the Castle spin off books too!
Plus so many more I'm too lazy to right about.
As for hitchhikers I'd recommend the originals over the books.
I'm going on holiday on Sunday, I'll either be reading Sanderson's Way of Kings, Weeks' Black Pirsm or making a start on Joe Abercrombie's trilogy depending on what the book shops are willing to sell me.
