On a foggy morning, thirteen year old Jessica wakes up in a strange forest, not knowing how she got there, but with a feeling she is being watched. Helped to a local police station, memories start to come back, about where she has been the last few days... She remembers a deal she had to make to stay alive... to obtain a small bottle of vampire's blood. With the use of a magical phone, her journey takes her to the English Lake District, a lonely Scottish village and the bright lights of New York. She meets mysterious men who work for a secret government organisation and a vampire who seems willing to help, but is he and his teenage vampire friends to be trusted? On the run, she must reach a government hide out before her adversaries catch up with her and take her to a realm of darkness and blood...
