I finished the whole Sword of Truth Series. It took forever and about halfway through every book I said I wasn't going to read any of the others. But by the end I decided to go ahead and read the next one. I think it was because I liked some of the main characters enough that I wanted to know what would happen to them. There were a couple books that were better than the others too.
Oh, and I've read all of the Dragonriders of Pern books, at least the ones written by Anne McCaffrey, not the newer ones by her son. They are awesome! I also love her Crystal Singer Trilogy...I've read it several times!
