 My biggest complaint with the previous two books in this series was the fact that these books were a little bit too much youth fiction. The writing was very simple and descriptions were a little bit too forced. And while book 3 did have similar problems, the story line was much better than it's predecessors. It wasn't just a rinse and repeat with the whole there's a spell and we have to find all the items adventure. This time the adventure went through our world through Europe and Conner has to follow clues that the Mother Goose left behind to see if the portals really are closed for good. Because if they aren't the Land of Stories is in for a very gruesome situation.
