The dual narrative is a neat feature, but it causes really short chapters. The narrative itself isn't bad. The story isn't wrapped up neatly with this book, though, you need to keep reading in the series (I assume, I've only read this first book) for some details to be concluded. There is definitely a cliff hanger at the end of the book that will probably floor kids, but about which adults will likely be able to take some decent guesses. Overall, I recommend.
