Well, I don't know what you've read. But I would suggest anything da
link, especially the Disc World series-- very funny stuff.
link is also brilliant. He wrote Stardust, which was made into a movie a anno o so ago, and he also wrote Coraline (which was turned into a movie that came out this year). But he's also written things like American Gods, Anansi Boys, and Neverwhere.
For a book da both Pratchett AND Gaiman (two brilliant minds working together), I'd recommend
link, a comedy about the apocalypse, a pair of unlikely Friends (a demon and an angel), and a misplaced Antichrist.
I'd also suggest Philip Pullman's
link series, which is very popular. The first one was made into a movie which was released a anno and a half ago.
As for più obscure writers, Australian autore Isobelle Carmody has a fantastic series called
link.
I hope at least one of these recommendations were helpful for you. I don't really know SPECIFICALLY what type of fantasy you're interested in, so I tried to provide a sample of a few different types (Comedy, Adventure, Magic, etc) for te to sift through.
