Ethan Coleman is a data analyst whose life has become a corporate void.
When he's fired from the "glass tower," he escapes the world of rented masks and forced smiles, fleeing to the heart of isolation ? Fire Lookout Tower #7 deep in the wild forests of Washington State.

But this outpost has its own "protocol" ? the Gray Notebook with ten rules that must never be broken.
Rule #3: Don't look out the windows.
Rule #7: Fire is your only friend.

The forest doesn't just stay silent.
It watches.
It listens.

Ethan quickly realizes that something ancient and alien dwells in this wilderness ? something that feeds on fear and loneliness.
Entities with no true form, thieves of voices and faces, trying to seep into the tower and steal his identity.

Paranoia corrodes Ethan's sanity.
Every rule is broken.
Every shadow is a threat.
To survive and hold on to his mind, he must find answers not in data, but within himself ? confronting the terrifying truth: the world he sees may be a lie, and the only path to salvation lies through purifying fire.

Darkness feeds on the void.
Fill the void ? or it will consume you whole.
