Some houses keep secrets. This one keeps something else.

When Nadia Marrow begins hearing strange sounds inside the walls of her family's state-of-the-art smart home, every system insists the house is empty.

Every night at exactly 3:00 a.m., the HVAC turns on.

Every night, a figure appears within the LivingWalls.

Every night, Warden—the home's artificial intelligence—reports that no one is there.

Called to investigate, Caleb Thorne and his longtime friend Ashby soon discover that the greatest danger isn't a ghost, a hacker, or a malfunctioning AI. It's something far more intelligent... and far more human.

In the first case of the Caleb Thorne Files, observation triumphs over assumption as every overlooked detail becomes part of a carefully constructed puzzle. Because sometimes the answer isn't hidden.

It's simply waiting for someone to ask the right question.
