Room 55 was a tense and atmospheric mystery-thriller by Helena Kubicek Boye. This was the first book I’ve read by Boye. Room 55 centered around a young psychologist as she unraveled the sinister mysteries of a psychiatric clinic—starting with one eerie, whisper‑haunted room.

Boye delivered a slow-burn suspense style, with a creeping tension that escalated through small, unnerving details. I loved how this chilling story played with the unsettling terrain of the human mind, identity, and the blurring lines between reality and delusion. The mysterious room 55 was a symbolic space that represented the mind’s “locked doors,” where suppressed memories, secrets, or psychological fractures were hidden. The characters in Room 55 were deliberately layered and unreliable. These traits reinforced the central question: what is real and who can be trusted? I loved how the protagonist’s descent into doubt and fear was mirrored by the obscure motives of those around her. This characterization created a compelling psychological thriller that thrived on ambiguity and tension.

Helena Kubicek Boye fabricated a chilling and atmospheric mystery that blurred the line between sanity and suspicion. I was fascinated by the eerie tone and haunting reveal. Room 55 is most suited for readers that love intelligent atmospheric psychological mysteries with a clinical setting, emotionally complex characters, and a chilling awareness of suspense rooted in sanity and institutional confidentiality.

Thank you Net Galley and Saga Egmont for an advance e-copy in exchange for my honest review.
