Fancy a cup of magical tea? Come in, sit down, relax. Don't mind the killer in the corner... All Emma wants is to sell her enchanted teas in peace; instead, she's caught up in the chase for a killer who's stalking the streets of London. He's targeting half-bloods, people with limited magical ability. People just like Emma. The police are baffled by the long string of deaths, but they're not willing to put in the legwork to make an arrest. After all, magic users can take care of themselves, right? Except, those with real power don't give a damn about half-bloods. So, when Emma wakes from a strange dream that nearly gets her killed in the waking world, she knows she has to deal with it herself. She's not alone. Gibble, her Boggart shop assistant has her back. But can she trust the two strange men that turn up on her doorstep, claiming they want to help? The sun is going down and the killer is just around the corner... and Emma had better find a way to stop him.
