I like the name of the book, but that's it. The wardrobe from Narnia meets the Grimm Fairytales for Halloween. The character's actions seem staged and forced by the narrator, who at times tries to be funny, but not really.
I know it's a children's book, but so is Harry Potter, or Chronicles of Narnia for that matter. Many I've set my expectations too high. Oh well, not everyone can be Clive Staples.
