Twenty-seven years ago, a fire on the thirteenth floor of the Harrowgate Hotel took Vera Sloane's mother. The floor was sealed, erased from the directories, and forgotten by the city. Until now.
When preservation architect Vera is hired to survey the condemned level, she expects ruined plaster and water damage. Instead, she steps into a pristine, impossible replica of her childhood home.
Malcolm Vane is the enigmatic buyer who acquired the floor to protect a dead man's legacy. He knows why the rooms exist. He knows what they hide. And he knows that the surveillance cameras hidden in the fixtures are watching their every move.
When a suspicious building lockdown traps Vera and Malcolm on the thirteenth floor, they are forced to unravel an architectural conspiracy that spans decades. Her father built the rooms as an underground sanctuary. Her mother died protecting them. Now, Vera must trust the man guarding her family's darkest secrets to survive the people trying to bury the evidence forever.
But the thirteenth floor isn't just a time capsule. It's a trap. And the doors are already locked.
