The Violet Crystal - The Chronicles of the Ancients, #1

The Ancients have not been seen in the world for roughly 1000 years. These legends helped shape the new world after the Great War and then slowly disappeared into history. Trouble is stirring in the kingdom of Carlisle and young Prince Morgan isn't ready to lead. His mother has been attacked by some uknown enemy, a stranger has appeared with strange abilities, and his capitol is under attack with its citizens turned into mindless puppets.
The motives of the hidden enemy remain unknown, but Prince Morgan is soon joined by other mysterious figures who seem to be akin to the Ancients of old. Are they the actual storied Ancients? Prince Morgan somehow must trust these strangers as he flees for his life while he also struggles with his newfound powers. Will he be able to harness his magic and save his kingdom?
