Fifteen phones were locked inside the manager's safe.

The sixteenth was already watching.

Detective Leane Case was supposed to be off duty when her family arrived at an isolated luxury lodge overlooking Snoqualmie Falls. For one week, eight relatives planned to escape their routines, repair old relationships, and prove they could survive a gathering without arguments, distractions, or secrets getting in the way.

Then the storm closed the mountain.

With the road blocked, communications failing, and every personal phone sealed away, the lodge becomes a beautiful prison. Its eighty-nine rooms stand empty. Its fireplaces burn without guests. Its hallways stretch beyond the reach of the emergency lights.

When the first body is discovered, the murder is too carefully arranged to be an act of panic. It is a message-but no one can agree on who was meant to read it.

Leane takes control of the investigation while suspicion fractures the family. Every victim exposes another hidden relationship. Every witness remembers something differently. Every clue points toward someone with a believable motive, yet each answer creates a more impossible question.

And somewhere inside the lodge, a mysterious cell phone continues recording.

It captures conversations no one remembers having, movements no one admits making, and images taken from places no person should have been standing. As the family and lodge staff disappear one by one, Leane must determine whether the phone is documenting the murders, predicting them, or inviting the survivors to participate in something far more deliberate.

Everyone came to the lodge carrying a secret.

Someone came carrying a plan.

IF EVERY CLUE IS TRUE, WHY IS EVERY SUSPECT WRONG?
