The clock has finally run out for the Cahills. As the leaders of the most powerful family, Dan and Amy have been in the crosshairs for too long. It was only a matter of time until luck failed them.

Media tycoon and presidential candidate J. Rutherford Pierce has set his sights on destroying the siblings. And after numerous close calls, it looks like he's about to get his wish.

Now Dan is hopelessly trapped and nothing can save him. Nothing except unleashing an evil the Cahills have spent centuries trying to hide.

The Cahills have always had a secret weapon, but it comes at a great cost. With everything to lose, Amy has to ask herself the question that haunts her nightmares:

Just how far is she willing to go to save her little brother?
