A vampire with a grudge has kidnapped Harry's daughter. A daughter he never knew he had. Furthermore, this vampire plans to use her blood in a violent ritual sacrifice - designed to kill Harry, his ex-partner Susan and their child.
As allies are perilously thin on the ground, Harry must find a new source of strength. In the past, there had always been a line he wouldn't cross, and he's never given in to the full fury of his own untapped dark powers. But then, only his own life was at stake.
