The Kingdom of Endara is at war. Eirian's allies are too far to keep the enemy from crossing the border into the Kingdom, and Queen Eirian refuses to be the soft-hearted queen the enemy expects. Behind rival lines awaits a force as old as the world they inhabit. One that seeks to destroy everything in its quest for revenge. The arrival of a mysterious king and his army spurs the real enemy into revealing themselves. Eirian knows it is her duty to stand against the oncoming darkness, even if it costs her everything. Duty to her kingdom has always been her driving force, and Eirian knows she can buy the precious time needed for reinforcements to arrive, but she will have to break promises she made to the ones closest to her. To keep her freedom and save her people, Queen Eirian will do whatever she can to buy time until reinforcements can reach them. Among her growing collection of secrets is one that can help turn the tide of battle, but it means showing everyone why they should fear her magic powers... and her people might turn against her.
