In the final chapter, it is a time of great strife for Boston high-schooler Ryan DuLac and Merlin (aka Matt) as they struggle to stem the flood of destruction unleashed upon the world. Their only hope rests in the one object that can restore their greatest ally: the Healing Cup. With every scrap of life hanging in the balance, Ryan must convince both friends and enemies that the key to survival rests in the plans of a sword-toting girl of only eighteen. She must reconcile a fifteen-hundred-year rivalry between two brothers, and be ruthless enough to break a heart--and a life--in the process. And at some point, she really needs to get herself to Prom.
