In this book, Megan and Ainsley, two teenagers from Earth, are transported to another world, the world of Arylon. Before they can return to Earth, they have to stop Evren from taking over all of Arylon. Unfortunately for them, Evren has the power to control people's minds. Megan and Brighton, a thief who has been cursed into the form of a ferret, are the only two characters who can resist the mind control. The three of them run around trying to undermine Evren. When they reach the unicorns to try to get their help, one of Evren's minions show up, and they end up having to escape from the unicorn's glade by means of a portal that Ainsley creates. They then go to the port where Evren has set up his head quarters. Megan is kidnapped by one of Evren's minions, who is planning to sell her in Obonia. When they get to Obonia, she escapes with the help of her friends. Unfortunately, Ainsley is captured for being rude to the chieftaness, and Megan must challenge her for his freedom. She succeeds, and then heads back to port to kick Evren's butt. When they get there, they have Obonian warriors to help them defeat Evren. They get to Evren's HQ, they go inside and Ainsley is turned against Megan by Evren. She turns him back, gets Onaj's Horn, the item Evren is using to control people, and destroys it, therefore freeing everyone Evren was controlling.
