Tri-System Authority – serie

Jason is not a child anymore. He hasn't been a child since the King betrayed his family, but everyone still treats him like he is, tucked away and protected as the heir to the Falconbone family. He dreams of the day when he finishes his ship, The King's Regret, and flies it to the capital to avenge his mother. When Father flies away to search for allies, a saboteur wreaks havoc on their refuge, and Jason is determined to find the traitor. The last thing he expects is to discover his family's oldest enemy lurking in the shadows of their mountain hideaway. And for that man to be his only hope for bringing his Father home alive.
