Creepy descriptions of ghosts, the Catacombs, and a vengeful spirit chasing the protagonists.
The book deals with death and the afterlife through a secular, supernatural lens. The ghosts are depicted as spirits trapped by trauma or unfinished business. The approach to death is direct but fantastical, focusing on the mechanics of 'ghost hunting' rather than religious theology. The resolution is hopeful, emphasizing peace for the restless dead.
A 10-year-old who loves urban legends and spooky stories but is also navigating the 'older kid' transition of being responsible for their own actions and mistakes.
Preview the scenes in the Catacombs (Chapter 6) and the final confrontation with the poltergeist. The imagery of 'The Boy in the River' can be quite unsettling for sensitive children. No heavy context is needed, though knowing the basic premise of book one (City of Ghosts) helps. A parent might see their child struggling with a secret mistake they are afraid to admit, or notice a child who is becoming increasingly fascinated by darker, gothic imagery and history.
Younger readers (8-9) will focus on the 'scary monster' aspect and the cool Parisian setting. Older readers (11-12) will pick up on the tension in Cass and Jacob's friendship and the ethical dilemma of what it means to be a ghost in a world of the living.
Unlike many ghost stories, this series treats ghosts as complex characters with their own agency, and uses real-world history and geography to anchor the supernatural elements in reality.
Cassidy Blake is in Paris while her parents film a TV show about haunted history. While exploring the Catacombs, Cass accidentally awakens a 'poltergeist' (a malevolent spirit) who begins to cause chaos and drain energy from the living. With her ghost best friend Jacob and a fellow 'In-Between' friend named Lara, Cass must find a way to put the spirit to rest before it becomes too powerful to stop.
