Still recovering from the case of a serial killer spirit in Lyme-Regis,
Dr Ribero's agency is soon confronted with an even greater threat: a
reckless cult conspiring with an ancient and powerful Daemon to open a
permanent spirit door so that spirits have unfettered access to the
human realm. Having just witnessed the lethal consequences uncontrolled
spirits can have on the unsuspecting, the agency joins forces with
several others to prevent the cult from unleashing chaos and ending the
world's fragile protection from dangerous spirits.
