What the keys unlock

Elara Finch is a ghost in her own life, a modern-day recluse hiding behind a wall of cold, analytical silence. Her quiet existence shattered when she inherited a brass ring holding seven mismatched keys and a slip of paper bearing a single address in the labyrinthine city of Oakhaven. Each key unlocks a door to a hidden room within the city's ordinary-looking buildings, revealing grotesque, impossible secrets: a library where books bleed, a parlor where clocks tick backward, and relics that defy physical laws. Guided by an uncanny, obsessive intuition that allows her to trace the resonance of these strange anomalies, Elara is drawn into a dark, unfolding puzzle. But she isn't just looking for answers; she is hunted by an unseen presence that wants the secrets kept locked. To survive, Elara must piece together the truth behind her inheritance before the final door unlocks her own destruction.
