📝 Description: The Unknown

This psychological thriller centers on the unsolved mystery of New Avalon. In 1926, five women vanished from this remote Vermont island, leaving behind only their dresses hanging from an oak tree. A century later, struggling actress Marin Keane accepts a role in a film about these events. Her preparation requires a research trip to Lake Faraday, where she joins legendary actress Violet Wright and director Ronan Peters. The cast discovers that New Avalon was once a commune for spiritual mediums. Local lore suggests a séance gone wrong summoned supernatural forces, a theory supported by Daisy Rue’s diary. As the group investigates, strange noises and mysterious symbols appear. A health emergency strands them on the island, and the disappearances begin anew. Marin relies on Daisy’s writings to understand the past while fearing for her own safety. This large print edition suits readers who enjoy suspenseful narratives rooted in historical mystery and supernatural horror. It appeals to fans of isolated setting thrillers and those interested in early twentieth-century spiritualism. The story does not suit readers seeking lighthearted romance or fast-paced action without psychological depth. The narrative focuses on the tension between natural explanation and paranormal possibility as the cast confronts their shared fate.

Horror desk
Riley Sager presents a novel centered on the unsolved mystery of New Avalon, blending gothic atmosphere with psychological thriller elements. The large print format enhances accessibility for those preferring clearer typography while engaging with themes of spiritualist communes and vanished lives. However, this book does not suit readers seeking lighthearted romance or fast-paced action without psychological depth. The narrative relies heavily on the slow-burn tension between natural explanation and paranormal possibility. It is ideal for audiences comfortable with historical trauma influencing present danger, but may disappoint those expecting immediate gratification or straightforward supernatural action over complex character-driven mystery.

Very good

Was skeptical at first. It is the kind of horror that rewards reading with the lights on. My only quibble is that the middle third sags a little. Solid, if not essential.

Slow start

Needed a good scare and got one. Not a jump-scare book; it gets under the skin and stays there. It is the kind of horror that rewards reading with the lights on. My only quibble is that the middle third sags a little. Recommended with reservations.

Dread done right

Wanted something for October and it delivered. The setting is practically a character, and a hostile one. The ending is bleak and honest, not a twist for the sake of one. Highly recommend.

Almost perfect

Took a chance on it after reading the description here. A few scenes I will not forget, whether I want to or not. Delivery took a bit longer than quoted.
