For millennia, the vampires walked the earth undetected, feasting on humans in keeping with ancient tradition.In the Information Age, vampires realised they must be more careful to avoid detection. In the late 20th century they created the global Vampire Federation to police vampire activity, with special agents like Alex Bishop authorised to hunt down her own kind who break the laws. The old traditions are history.But not all vampires bow down to Federation rule. When rebel vampire Gabriel Stone declares war against them, Alex and her team are plunged into danger.Police inspector Joel Solomon, haunted by a secret terror of vampires, discovers a series of corpses left behind by Stone's bloodthirsty gang. As he and Alex are drawn together in an unlikely alliance between human and vampire, the race begins to destroy the evil Stone before his uprising tears their world apart.
