The Ghost Ring: Lost Souls of Caligo Falls by Tom Hoffman is book 5 in the series. Simon Moody and Clara Barley are ready for a quiet summer in Caligo Falls until attorney Marion Jaggers hands them their first paid job: a derelict Manhattan hotel, abandoned since the 1920s, which is home to two dangerous spirits and a brass key to Room 714, a room that officially doesn’t exist. What starts as a simple eviction quickly deepens into a tangle of forgotten letters, a Briar Hill Road cold case, and the unsettling history of Henry Allistair Blackwell, the hotel’s reclusive owner who vanished without a trace. Their search leads from soot‑stained corridors to an uncharted village in the Congo Basin, where the Bakala tribe’s Nganga guards a secret older than the hotel itself. Before summer ends, Simon and Clara must uncover the truth behind Room 714 and free the spirits still trapped inside.
The Ghost Ring: Lost Souls of Caligo Falls by Tom Hoffman is a fun, family-friendly paranormal mystery, squarely middle-grade/YA in tone, with nothing here beyond a mild spooky atmosphere and some historical peril. Simon and Clara carry the book well as leads; their rapid-fire, joke-cracking banter is the heart of the series, and Hoffman clearly knows how to write teenage chemistry that feels warm rather than saccharine. The supporting cast adds real charm: eccentric attorney Marion Jaggers, who communicates almost exclusively in cryptic instructions, the deadpan Sergeant Rogers (who has, delightfully, deputized a stray cat), and the ever-mysterious caretaker Harrington. The ghost at the center of this book, Henry Blackwell, gives the mystery real emotional weight; his backstory, unfolded gradually through letters, photographs, and a Congo River expedition, is genuinely engaging and elevates this above a simple haunted-hotel romp. The pacing is brisk and puzzle-driven, with hidden safes, coded journals, and secret passages, which will appeal to readers who like their mysteries interactive and clue-based. Younger readers new to the series might want to start from book one for the full context on Simon and Clara's history, but this entry stands reasonably well on its own. If you're looking for a clean, funny, adventure-driven ghost story with genuine heart underneath the jokes, this series is perfect.
