But when Kal unexpectedly makes an appearance, her safe, dependable existence is shattered once more. Drawn into Kal's deadly world of vampires and demons, she must now put aside her hurt and anger and learn to trust him. Can she forgive past deceptions and find the courage to love again?

As fate tosses them together once again, Kal must fight to win Katherine's trust and forgiveness before evil separates them forever. But is he ready to become the man she needs him to be? Or will he lose the one woman he can't live without?
