This book was just another "fine" book in this series, but it feels like an afterthought to the original three books, which featured characters that were in the first book, all in Las Vegas together. I'd say this was just average, especially because these two were such a random addition the world that was originally built. It was just mediocre and overall, I really think this series was a huge letdown. It had such great potential but almost every book fell totally flat and I just felt so BORED.
