The books good but not great. Cool ideas but the writing could be better. My friend read a lot more of them than I did and after the original author died another guy picked up where he left off and those ones are apparently better.
You should just read the Sword of Truth series by Terry Goodkind though. Disney tried to make a TV series about it and they fucked it up real bad.
Edit: wow people are really offended by my opinions of some fantasy novels. Sorry, everyone.
