London. Now. Terrorism is rife, but after today, your life may never be the same again. A ballerina, Romany, gets on a train in the London Underground, a strange gas attack turns her into a half-dead vampire. During the contaiment and cleanup of this attack, she's captured by a government agency formed to battle the vampire threat, PASA (the Bureau of ParaHuman and Supernatural Affairs). Romany's a remarkable subject, and after some training she is paired with her handler, Ian, also one of a very few survivors of a vampire attack. Ian turns her into a force to be reckoned with... The cogs of an evil machine are turning within the winding streets of London; disaster looms on the horizon; they can strike anywhere at any time. What is PASA willing to do to stop them?
