This is fun story. The characters are not flat, though only limited development over the book.

Grand-mama X and her cats are in some ways better characters then the main twins Jack and Jade. While the story isn't transparent it's could have been much more original.
If you or your kids have issues with (not graphic) descriptions of ants, bugs, rats and white eyes this would be one to pass. Evil is much more clear then in Keys to the Kingdom.
While I'm sure I'll enjoy the next book. I hope that Garth decides to go back to writing solo.
