Gripping, atmospheric and sexy, this is British horror at its best.

Kathy Bilic is adopted. Until now, she's had only a vague memory of her real family.

But terrifying dreams and visions of her sister Amber are waking her in the night.

When Amber starts giving her messages, Kathy gets a sickening sense that her sister is in danger - from a deadly, inhuman source.

Kathy hits London to find her sister - but when she arrives at her aunt's house in Highgate, she is actively dissuaded from pursuing the mystery.

Undeterred, Kathy's trail leads her through a bloody murder in the British Museum to a charged meeting with the mysterious, hypnoptic Antwain and a final confronation with her sinister father.

Before long, Kathy uncovers the full horror of her heritage and her sister's fate at the hands of the Vampire of Highgate.
