Prisoner of the Blood I: Insatiable

Seduced and killed by a beautiful woman, Richard Venneman wakes as a vampire. Loathing what he has become, horrified by his own irresistible need for human blood, he seeks salvation via self-destruction. He tries to incinerate himself in the experimental fusion reactor where he worked when he was alive. But instead, the machine's energy beam transforms him into something even worse than a vampire.
