Mercy of the Vampire King

What kind of fool begs mercy from a vampire, even if he is a king?
With my title and those I protect in jeopardy, and blood traitors just waiting in the wings to steal what is rightfully mine, I have no choice but to attempt the impossible. I must beg for the vampire king's aid.
But nothing prepares me for what I feel when I arrive at his dark castle. His scent lights a fire in my very soul, and it seems my blood sings to his in ways he's never felt before, because the ancient and gorgeous king, Knox, grants me his mercy.
He'll help me maintain control during these treacherous times-but at what cost? When the Outsiders return to lay claim to my country, all our lives hang in the balance and suddenly an inheritance is the least of my concerns. I'm prepared to do whatever it takes to save my people... but will the price Knox demands of me prove higher than I can possibly pay?
