In the Necroscope series, readers saw Harry learn to use his powers to talk to the dead and travel instantaneously to any point in space and time. They saw him take arms against the evil, twisted, metamorphic alien vampires who sought to feed off humans and enslave mankind. They saw him suffer a great personal loss and then recover his family, and later his humanity, through a new love. And they saw Harry wage the grimmest battle of his life - against the vampire he himself was becoming!'
