"Follow my instructions, and when our task is done, I will release you."

Commanded by the magical artifact known as the Dragon's Eye, junior con artist Callan and his friends are eagerly reaching the end of the epic quest that will finally free him from the Eye's sinister hold. But their final task is their most ambitious: sneaking into the emperor's private island prison and rescuing a man from a jail cell that has been locked tight for a hundred years. This impossible heist will strain the gang's unique abilities to thieve and deceive everyone from the guards, the city elite, the warden, and even the nefarious local crime boss who warns them to stay away.

As the friends plan out their last and most difficult con job, Callan begins to question what they're helping the Eye to achieve. Aided by magical hints and fitful dreams, Callan slowly uncovers the Eye's true desires. To his horror, he realizes that he may be the one being conned all this time . . . and his mistake could cost the world's entire existence.
