When ghosts began popping up, haunting & terrorizing the people of England, it created a need for ghost extermination services. That’s now the job of Psychic Detection Agencies, who have operatives trained to deal with these dangerous beings. However, psychic abilities fade as one gets older, and so it’s young children & teens who must do the dangerous and often fatal work.

Lucy was a pretty good agent at her old job under an established agency, until a job gone badly wrong left her as the sole survivor of her team. Looking to start over at a new Agency in London, she joins a tiny, barely surviving firm, run by & staffed with only two other employees about her own age. Desperate to keep their firm afloat, Lucy and her two new friends take on a high risk job that most established agencies have lethally failed at before.
