This book is perfect for kids that like magic and mystery. My boy loved reading it . The map of the school was a great addition. Wish there were few more illustrations throughout the book but apart from that he really enjoyed it. I truly enjoyed reading it myself and I could easily read it in a day. I like the main character Ella and felt a little sorry for her in the beginning when most kids didn't like her and didn't want her there . She found two best friends who's helped her realise she has as much right to be there as any other child. Just as she settled something very bad happens. The most dangerous person alive Gia mysteriously breaks out of unbreakable prison and seeks revenge. Ella's favourite teacher mysteriously dissapears too and no-one knows what's happened to him. Ella and her friends find a way to track him down and go on an adventure to save him but what they discovered was a big surprise for everyone. Overall a great book that I would recommend.
