The King was dead.

His body was found slain in his room, only months after his son had been brutally murdered. Skylar Mandolyn, his daughter, has now become the last heir to inherit the throne. But instead of becoming Queen, she has been imprisoned for helping in the escape of Sir Harlin Brien, her knight who was framed for the King’s murder.

Confined to darkness, Skylar's captors have given her no choice but to yield to a new kind of enemy: a kingdom that has advanced in both technology and warfare. It's when she refuses that the prison uses its other means of persuasion, and although unmerciful, the whip lashings and isolation can't suppress the memories of her family's downfall. Pulled between her subconscious and reality, Skylar already knows who the true enemy is, because even the darkness can't hide the deceptive hands that have destroyed them all.

With two kingdoms on the brink of war, Skylar's only hope is in the person who has gone missing—Harlin, the knight who was sworn to protect her. The memory of him surrounds her when the darkness screams louder than the prisoners, and when Death smiles a faceless grin in between the cracks of the stone. While the tremors start to rise from the deep, crawling up through the prison's walls, Skylar will soon see why he's one of the benighted.
