With the only man to stop him miles away from the mountain prison in which she is kept, she must now choose which path to take in order to survive. With enemies at all sides closing in quick, she must tread carefully or she might find the only man to save her isn’t the White Knight she loves but the Dark King she loathes. But time with the Vampire King is dangerous and Keira soon learns that it is more than just the power of her mind she needs to keep locked but also the power of her heart…
And Lucius might just hold the key to both.
