When rebellion erupts within the royal bloodline of Dernancourt, sixteen-year-old commander Griffith Ryeland is forced onto the battlefield sooner than anyone expects. Gifted in strategy and loyal to the House of Yi, Griffith stands beside Prince Yu-Jun as rival princes move to seize the crown, and the future of the realm hangs in the balance.

Outnumbered and surrounded, Griffith must rely on cunning, discipline and deception to turn certain defeat into victory. But war is only the beginning. As traitors are brought to justice and peace returns, new threats emerge in the shadows of the Imperial Court: threats that cannot be faced with swords alone.

From brutal battles and court intrigue to secret legacies and forbidden knowledge, Dernancourt is a tale of loyalty, honour, and the cost of leadership. As Griffith’s path leads him from war to love, from soldier to steward of a greater destiny, he must decide what, and who, he is willing to protect.
