I really recomend the series wig. Firstly, it adds new and fresh ideas into the fantasy world (I won't spoil) and though it is based upon historic facts, there is no fear from the author to change them. Considering that this is her first series of bookss to be published it is a very strong start and somthing that I am a keen follower of (when one comes out it gets to go to the top of the reading pile).
And if you don't belive me then belive Peter LorT Jackson - he has even considered making into a film (so now you have to read it before the media get thier paws on it)
