Private Investigator Nikki James is in San Francisco at the request of her business partner and best friend, Jake. His friend's wife is missing, and he is determined to find her. The authorities believe the kidnapping is the work of a sick mind; Nikki knows it is something much worse. Vampires. Six of them. And they know who she is and why she's there.
Michael Kelly has just returned from a vampire hunting exhibition in his homeland. When he discovers Nikki's gone to San Francisco, he has no choice but to follow - not only to keep her safe from the vampire gang, but because he fears the psychic talents she's beginning to develop; abilities she should not have and cannot control. But as the body count begins to rise, so too does the danger. Soon Nikki becomes a target, but she has no intention of obeying Michael's demands that she leave. She's tired of playing it safe and wants him to realise it's all or nothing: she's either a full-time partner in his life, or she's out. Nothing, however, prepares Nikki for the price she has to pay for her stubbornness the life of someone she loves.
