This book in my opinion was an enjoyable read, but it definitely surprised me when it came to the movie interpretation. The movie is actually over the events that took place between book one, "The Isle of the Lost" and book two, "Return to the Isle of the Lost". The end of the first book is how the movie, Descendants begins. It starts with the villain kids running throughout the streets of the Isle being rotten, and king Ben of Auradon having an idea. The second book gives a brief description of all that took place between then and the beginning of the second book, and often references these events.
This was a unique idea for the movie, to show events that were not explained in detail in the story. I honestly think it would be a great book to bring into the classroom because of this. The teacher could show the movie before getting into the book in order to give background information on the main characters. Then they could use that to have the students find detail in the book that was used in the making of the movie. For example, the book explains how in Auradon the use of magic is discouraged, and that's referenced to in the movie. Finding these details can help teach students to find context clues.
Also, before starting the book, the students could make inferences on what they believe will happen to the characters based on the events in the movie. There are many other activities that can go along with the book, and I believe it's an appropriate read for middle schoolers. Overall, Melissa De la Cruz did a great job on creating a fun story for Disney fans.
