I am interested to see how book 5 goes as this one appeared to be the calm before the storm. A builder for the finale in a wholly different way. We get to know much more about the earth spirit and what is really going on in the world as well as the history. This one had some areas that were a bit of a trudge but overall the storyline and is great and love the characters. You can tell that war is coming. Thinking that book 5 should be epic.
