Courtesy of The Powers That Be, Cordelia Chase has grown used to her excruciatingly painful visions, but that doesn't mean that they leave her unmoved.

Alone with her on a small and distant island, Escobar had been working to find a cure. Before he could succeed, however, she escaped him, and now he suspects that she is the creature stalking Faith.
But Escobar has a hidden agenda, and before long Angel, Cordy, Wesley and Gunn discover that his real aim is to rid the world of vampires -- all of them, forever; even those who possess a soul.
