Ok, when I got this book, I had heard it was great from a woman whose daughter had read it. I had no idea that it is the prelude to a Disney Channel movie. I have, however, read and enjoyed other books by this author. The concept behind this book, and the movie is that all the Disney bad guys were banished to an island where they could not practice magic and they had kids and the book is about their kids. For some reason, probably because they are evil, the adults all seem to be single parents, who are trying to raise their kids to be as evil as they are, but the kids may or may not be as evil as their parents. Mal, is the daughter of Maleficent, Evie is the daughter of the evil queen in the Snow White story, Jay is the son of Jafar, and Carlos is the son of Cruella DeVil. The book is a fun story to read and now I want to watch the movie!
