I loved this book. This is the type of book that I can't wait to read with my kids when they are a little older. It really reminded me of the Percy Jackson series and Harry Potter. Not because the stories are similar, but because the story is something kids can relate to and at the center of the story are reminders about the importance of friendship and family. 
 The story is primarily told from Jack Swift's point of view; however, it is a third person narrative so you occasionally get insight from some of the other character's when Jack is not in the scene. Jack is sixteen and posses magical powers, but because of medicine he takes, his powers have never manifested until the first day he forgot to take his medicine. Once Jack realizes that he is not who he thought he was, him and his friends are on adventure to help save his live. 
 This was a really fast and enjoyable read that people of all ages can enjoy.
