That prey is a vampire.

Venneman was the first vampire in history to transform himself into an even more terrible being who preyed on vampires. And then he was first to become a human again. Now he hungers -- not for blood, but to find a vampire who will make him a vampire for the second time.

His obsessions have forced others through strange transformations. Karen Belmont, trapped between human form and werewolf shape, hungers both for blood and flesh. Elizabeth VallT, content for three centuries to be a beautiful, seductive vampire, has become the stalker of vampires that Venneman once was - but monstrous in size and appetites.

Now Elizabeth wants an eternal soulmate and has chosen Venneman, while Karen is hunting him so that she can take revenge by tearing him apart. Their meeting will trigger a catastrophe -- for them, and potentially for all mankind.
