Difficult to give it a good rating, because the series is beginning to irritate me now. Very predictable. You know theres going to be an interdimensional portal, because thats what the last 3 books were about. I know theres going to be a portal, it's not scary or exciting. And Bo is all 'what are you talking about,theres nothing suspicious'. bah. shove a sock in his mouth and bend him over. The sex redeems the book.
