Faith of the Fallen is one of Terry Goodkind's best books. I know that this book contains lots of philosophy and moral issues, but all these things are still fresh and interesting, because Goodkind hasn't bored the reader with them yet. I have to admit that I like this book - the story is interesting and the writing is good.
Faith of the Fallen is unfortunately the last good book of the Sword of Truth series. The quality of the series began to drop radically after this book.
