The main reason I read the book was because it was free and I like magic in a totally non-nerdy way. The book was free, because it was given away as part of some literacy drive. The target audience for the book was young adult. I liked the technical aspects of the story. He flipped the perspective of the story from the brother to the sister for every chapter. Also the chapters were very short, which is good, when a person's reading time is sneaking off during an episode of Eastenders.
The author James Patterson has written a lot of books.
