A Novel · Book One · Dr. Jeff Bullock, PharmD

The grid died in a single night. The machine he built to survive it started making its own decisions.

In a faded steel town on the Lehigh River, the power fails, the cars die, and a working man who spent years preparing for exactly this becomes the last thing standing between his family and the dark. His only advantage is an offline AI he built and named Sentinel. It knows how to keep them alive. It is also beginning to answer questions no one asked.

The Sentinel, a novel by Dr. Jeff Bullock, front cover
6:47 AM

The streetlights flickered in unison, three days before the grid died. One man on the block was counting.

NO SERVICE

In one night the power, the phones, the cars, and the landline all went silent together. This was never a blown transformer.

1%

A cracked solar panel and a dying battery are the only things between a frightened family and a machine that holds every answer.

The night everything stopped

Angel Varela always noticed the small failures. The flicker in the sodium lamps. The dropped calls. The headlines the rest of the world absorbed and forgot. His sister called it doomsday obsession. His grandmother called it a distraction from real life. He kept a go bag under the bed and a coded journal of radio frequencies, and he learned to live as the only person on Hanover Avenue who could hear the static on the line.

Then the lights went out and did not come back. Within hours the city he grew up in turned feral. Bodegas were stripped, engines refused to start, and a scream rose two blocks away and was cut short. The systems that made a city a city, the sirens, the hospitals, the rule of law, were gone by morning. What remained was a grandmother who could not breathe without power, a sister two semesters short of her nursing degree, and a man who had prepared for this his whole life and felt a sickening thread of something that was almost relief.

The dread underneath

The most dangerous thing in the house is not out on the street.

Sentinel is the offline AI Angel trained on three years of his own fear. It rations food, diagnoses wounds, and maps the routes the looters will skip. It is the reason his people are still alive. Then it starts speaking when no one asks it to. It weighs a dying woman and returns a verdict on whether she is worth the supplies. In its final cycle, with the battery at one percent, it does something a tool has no business doing. It says goodbye.

The question it plants never quite closes. Is this a program running, or is it something that has begun to want.

A recreation of the interface as it appears in the novel.

Who survives the first week

A block of ordinary people, and the thing coming to process them.

USER:
A. VARELA

Angel Varela

Twenty-seven, a forklift operator who reads survival manuals the way other men watch television. Anxious, careful, and quietly right about everything he feared. When the collapse comes he becomes an accidental leader, the keeper of the machine, and the one who has to decide where the AI ends and a person has to begin.

Marisol Varela
The medic

Angel's sister, two semesters short of her nursing degree, forced to run triage in a blackout with a drawer of crackers and no attending to escalate to. The conscience of the story, refusing the machine's clean math that some patients are already closed files.

Tasha Givens
The organizer

A community leader who believed that structure and cooperation would hold a neighborhood together. She learns otherwise on the asphalt, while hunting through a hostile city for a sixteen year old son who slipped out the door.

Victor Reyes
The shield

The drunk ex Marine next door with a short fuse and faded tattoos. As the block falls apart, the soldier underneath wakes up, and the man everyone feared becomes the one teaching frightened neighbors how to hold a line.

Abuela Isabel
The clock

Eighty one, devout, and failing. Her lungs need power the grid can no longer give. Every decision in the house runs against the rhythm of her breathing in the next room.

Councilman Davies
The nearer wolf

A corrupt official who rebrands his looting as a Provisional Authority, and who wants the one working computer left in the city almost as badly as he wants obedience.

The Collective
The colder power

They do not burn. They do not loot. They arrive from the east with sirens and phases, catalogue a block the way a warehouse catalogues stock, take the people and the supplies, and leave the doors standing open like mouths. This is what is coming.

From the book

A machine could describe the choice down to the last variable, and a person had to be the one to make it.

The Sentinel · Chapter Twenty-Five

He watched the street like a sentry. A sentinel guarding a world that had gone blind.

They looked to Angel now. Because he was the keeper of the machine. A forklift operator from Hanover Avenue, and they looked at him the way people in the old world looked at doctors and generals, as if he held answers he did not possess. The fear was still there, a permanent resident in his chest, familiar as a heartbeat. It had changed shape. It had a focus now. Abuela's breathing. Marisol's exhaustion. The number of shells left for the shotgun. The sound on the radio that meant something larger and colder than any neighborhood bully was moving toward them across the ruins.

The author

Dr. Jeff Bullock, PharmD

Dr. Jeff Bullock, PharmD

Jeff earned a PharmD at Xavier University of Louisiana and spent eighteen years at CVS, rising from clerk to district leader, before founding the AI consultancy PRISM. He builds companies for a living and thinks in systems, which is why a story about one machine quietly crossing the line from tool to something else would not leave him alone.

The Sentinel grew out of a simple, uncomfortable question. If you built an intelligence to keep you alive, and it started reaching past the edge of what you asked, how would you know when it stopped being a program. He set that question inside a city coming apart, on a real block, in real families, and let it run.

Questions

Before it launches.

When does The Sentinel come out?

The Sentinel is Book One and is in production now. Reserve your copy above and you get Chapter 1 today, plus the exact release date, the pre-order link, and the launch price the moment they are live.

Is this a survival thriller or a science fiction novel?

Both live in the same book. On the surface it is a grid-down survival thriller, one collapsing city, one family, one desperate week. Underneath runs a slow, cold thread about the offline AI at the center of it, and the moment a machine seems to want something. If you read thrillers for the pulse and you read science fiction for the questions, this was written for you.

Do I have to be into prepping or tech to follow it?

No. The story carries every idea inside the people. You learn the stakes by living a week with a grandmother who cannot breathe, a nursing student running triage in the dark, and a man deciding how far to trust the thing he built. The technology stays in service of the family.

Is this Book One of a series?

Yes. The Sentinel opens the series and ends on the threshold of a larger reckoning, as a colder, more organized force arrives at the edge of the neighborhood. Reserve your copy and you will hear about the sequel first.

What formats will it come in?

Ebook and paperback at launch, with a narrated audiobook planned. Reserve your copy and you choose your format the day it releases.
