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 the throne. But instead of becoming Queen, she was 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 domain that has advanced in both technology and warfare. It's only when she refuses that the prison uses other means of persuasion. Though unmerciful, the whip lashings and isolation can't suppress her memories. She's forced to face again both her brother's death and her father's emotional decline, though even the darkness can't hide the deceptive hands that have tormented them all. Advisor turned adversary, Cross Lutherus has brought the ancient bloodline to its knees, and Skylar is the only Mandolyn left to feel his wrath.

With two kingdoms on the brink of war, and the end of her life drawing near, Skylar's only hope is in the person who haunts her the most – Harlin, the knight who was sworn to protect her. His presence surrounds her when the darkness screams louder than the prisoners, when Death smiles a faceless grin in between the cracks of the stone. And it's his strength she embraces just as the tremors start to rise from the deep, crawling up through the prison's walls to terrorize the benighted realm and all its souls.

The mystery was never how Harlin escaped. It is how he will return.
