AI summary

Lucy Carlyle is now a freelance ghost-hunter after leaving Lockwood & Co., but she is pulled back in by her former partner to investigate the 'Brixton Cannibal.' As the team reunites, they uncover a massive conspiracy involving the black market for supernatural artifacts and the highest levels of London's ghost-fighting agencies.

Parent notes

While the book features heavy paranormal themes and ghosts, it is a clean, well-written adventure that lacks sexual content or gratuitous profanity. Parent concerns: Occult/Paranormal themes (ghosts, spirits); Violence against supernatural entities and humans; Cannibalism mentioned (legendary background); Grave robbing/disturbing the dead Romance/sexual content: Clean romance; subtle attraction and emotional tension between main characters Lockwood and Lucy, but limited to professional partnership and protective friendship. One mention of a skull talking to a character like a 'jilted lover' is metaphorical. Language: Occasional British slang or mild insults; generally very clean for YA. Violence: Frequent descriptions of 'The Problem' (ghosts) and the dangers they pose, including lethal touches. Action sequences involve rapiers, salt bombs, and iron. References to a 'cannibal' ghost provide a darker tone than previous books. Substances: Tea drinking is a frequent social staple. No drug or alcohol abuse. Worldview themes: The existence of spirits/ghosts, Fighting darkness, Institutional corruption vs. individual integrity
