Manchester, 1993. The vampires of Great Britain have received a message: the long-awaited arrival of their evil messiah is imminent. It’s time for a recruitment drive. On holiday in Tasmania with Tegan and the Fifth Doctor, Nyssa is attacked by a demonic child. She escapes unharmed — except for two small wounds in her neck. Why are the descendants of the Great Vampire so desperate to obtain the blood of a Time Lord? And what is their connection to a forbidden ancient Gallifreyan cult?
