How far would you go to save your home? The dragon war is over, but Al's home is in more danger than ever before. Trejir, a powerful worker of magic, has taken over Castle Surflienne. The nearby city of Dockside lives in fear of its new lord. Citizens are kidnapped from the streets. Houses are robbed by the soldiers who should be protecting them. Al discovers that his mother is one of Trejir's victims, and is a prisoner in the castle. He flees into the Sunken City, searching for a safe place to make a plan, but Trejir has mercenaries there, too, hunting for him. Everywhere he turns, Al finds Trejir's men. His struggle to resist takes him through back alleys, haunted catacombs, and across rooftops. Along the way, he discovers that Trejir has a larger plan than just terrorizing Dockside, a plan that will destroy everything Al has ever known. Al doesn't know any magic. All he has is the sword his father gave him, and a determination to save his home. What chance does one boy with a sword have against the magic and soldiers of Trejir? Find out in this action-packed sequel to Dragon Run!
