As the fairies of Camp Fae investigate the disappearance of one of Alley Willowwood's closest friends, they discover that the entire magical world is on the brink of war. Someone is stirring up Pixies tribes not only against one another, but against the Fairies. Join Alley as she tries to find her friend and uncover the true villain behind it all in an adventure that takes her across several continents, deep under the sea, and to the other end of our solar system. Alley confronts kidnapping pixie tribes, dragons, a demonic beast from the underworld and more importantly her own fears as she tries to solve the mystery. Who are these mysterious new strangers that have appeared at Camp Fae and what are their intentions? Who has kidnapped her friend and why? And worst of all, what is she going to do now that she's inadvertently made an oath of allegiance to one of the pixie queens and quite possibly given her the ultimate magical weapon?
