(From the publisher):
Beneath Draqueen Castle lies a secret staircase to a forbidden room, and behind a hidden door lies ... well, no one knows, but it's probably pretty scary. The Dragon Knights are finally back home and at peace, but all is not well with the Kingdom now that Nadil is dead. His agents are on the rise, amassing an army to try to steal back Nadil's head. Meanwhile, a young demon is found inside the castle. Could he be a spy? Or is there really dissension in the demon ranks?
