Ever since he can remember, Sebastian Phillips has felt as if he is a special person meant to do something great. As soon as he turns eleven, he finds out why.

Even though he was born with cystic fibrosis, Sebastian still lives a normal life. But when Sebastian and his two best friends, Parker and Hunter—who are also growing up with lifelong illnesses—begin having a series of unexplained supernatural occurrences, they approach Sebastian's scientist father with the news. They are about to receive shocking news from Sebastian's father—they are members of a secret order controlled by The Book of the Phoenix and have been blessed with supernatural powers used especially to keep a balance between good and evil.

As The Book of the Phoenix leads them on a quest to attempt to defeat an evil witch in Norway, they soon uncover her true intentions and must use their special powers to stop her before it is too late.
