After five thousand years she was again mortal. The dead alchemists experiment has worked. Alisa is no longer a vampire, but a frail and confused human. Not only that -- she is pregnant. The baby grows in her at supernatural speed. As the stranger watches. The stranger from the past. But what child will Alisas seed produce? A demon or an angel? Alisa does not know. But the stranger does. He knows everything that ever was. And he knows everything that is to be.
