In the cliffside city of Gargoyle's Rest, the buildings are alive. And they are very, very angry. Oryn Fray is a "Structural Exorcist." She doesn't hunt ghosts; she tames rooms. In a vertical metropolis where architecture is sentient and blood is the only rent that matters, Oryn is the one they call when a house decides to swallow its occupants. Armed with a runic sledgehammer and an ear for the screams of load-bearing walls, she is a master of the city's concrete malice. But she's never encountered a job like Karr Manor. The house has gone rogue, sealing its creator inside. Malachi Karr, the city's Grand Architect and designer of lethal "Spite Rooms," is trapped within his own masterpiece. He is a man of cold geometry and precise cruelty, a man Oryn has every reason to hate. To save him-or to watch him fall-Oryn must enter a labyrinth of shifting corridors and shrinking ceilings. As they navigate the manor's treacherous geometry, Oryn discovers a terrifying legal loophole: Malachi may be the architect, but the house is the one in control. And the house doesn't want them to leave. Beneath the blueprints and the brickwork lies a dark secret that could bring the entire city crashing down the cliff. To survive, Oryn and Malachi must find a way to align their hearts before the house decides to crush them both. A cerebral, claustrophobic Dark Romantasy where the walls have ears, the stairs lead to madness, and love is the most dangerous trap of all.
