I enjoyed the story of this - i am still not a huge fan of the art when humans are shown. I like the ghosts and how they are drawn but especially the human faces... they just don't look very nice to me, nor do they bring anything to the story in showing emotion or anything to me. 

The story itself was nice thought. 
I liked learning more about Wendell and liked seeing him being treated better than he was in book two as well. 

I also enjoyed the ending of this book and i think it is overall a nice edition to the series. 

If you love this series so far, definitely read this.
