I liked this book because it was exciting with lots of mystery. The author added great details, especially when describing a person .For example a character may have short, brown, thick, flowy, straight hair. It helped me visualize each character and setting, as the story progressed. But the story wasn't perfect. It was really slow on getting to the point. Like the part where Oz was finding the obsidian pebble in his dads study, it took a lot of chapters to get to it. In conclusion, I would suggest this book to kids, teens, or anyone who is looking for a lot of mystery.
