If you're new, you might like something easy like the "gentle introduction to haskell" http://www.haskell.org/tutorial/. Unfortunately it does not cover more recent and advanced features; for that I would recommend Oleg Kiselyov's site http://okmij.org/ftp/Haskell/ (he is somewhat famous in the community for bringing advanced Haskell features "down to earth" with clear, simple examples).
