Through the eternal night of the Beyond, Gael carries his burden: two unfailing blades of steel along with a role he never cared for — executioner.

A prisoner of his own immortal body, he's haunted by memories of the woman he lost, and the only thing to keep him sane is the hope to find out the truth about her disappearance ninety sunless years ago.

Thrown off balance in a momentary flare of vengeance, Gael puts himself between the devil and the deep sea. His master and lord — the White Prince — knows a simple way to deal with treason. But death — the only means to escape the Beyond — is out of the question for Gael.

As he prepares the invasion of the Mortal Realm, the White Prince is driven by his past scars. Close to his victory, he's set his mind on keeping his best executioner by his side, and for the reasons he won't share even with his trusted sidekicks. Death sentence on hold, Gael has to prove himself the man to stand by the interests of the Chthonic kingdom.

Long numbed to his atrocious job, Gael dreads the new task as now he must choose between the nobility making him human and something his comrade in arms and only friend, David, calls a greater good — their chance at destroying the White Prince's hopes for invading the Mortal Realm.

Willing or not, Gael must act fast, for the mighty beast he's bound to, the one waking in the depth of the Somber Abyss, is nearing the point of his full power. Millions of lives at stake, Gael must demonstrate his unwavering loyalty, and through a soul-crippling task no less.

How far will he go for the sake of the greater good?
