Critical Acclaim
WHAT THEY'RE SAYING
“Sean Black writes with the pace of Lee Child, and the heart of Harlan Coben.”
Joseph Finder
NY Times Bestselling Author
“Black drives his hero into the tightest spots with a force and energy that jump off the page. This is a writer, and a hero, to watch.”
Geoffrey Wansell
The Daily Mail
“This series is ace. There are deservedly strong Lee Child comparisons — his character appealing, his writing relentless.”

THE REMOVAL
2026
A wealthy man's son is taken, and Ryan Lock is hired to bring him home — quietly, no police. He pays the ransom. The boy comes back. But the kidnappers were better than anyone should be, and the questions Lock can't stop asking are about to make him their next problem.
THE BURN PIT
The system used Byron Tibor up and threw him away — and he's not the only one. Among a band of veterans the country would rather forget, he finds something close to a home. Then a buried injustice drags the fight to their door, outgunned and outnumbered. They've already lost everything; all they need now is a spark.
THE YACHT GIRL
2025
Hired to audit security on a billionaire's secretive private island, Ryan Lock and Ty Johnson find a paradise with no cameras and no questions asked. Then they hear about the girl who vanished — and meet the people who'll kill to keep her forgotten.
TIBOR: WINTER'S RAGE
Byron Tibor has buried himself in a remote mountain town where nobody asks what he is. Then a young woman arrives with a cartel on her heels and a blizzard closing the only road out. He can keep his secret and watch innocent people die, or he can show this town exactly what he was built to do. By morning, only one of those is still an option.

LOCKDOWN
2009
It's Christmas in New York, and ex-soldier Ryan Lock has one job — keep a ruthless biotech CEO alive. Then the killing starts.
POST
The government took a soldier and made him into something that doesn't feel fear, doesn't feel pain, and doesn't break. Byron Tibor was supposed to be their perfect weapon. Now he's walked out of the lab and he just wants to get home to the woman he loves. The only problem is the people who built him can't afford to let him go.
DEADLOCK
2010
Ryan Lock is locked inside California's most violent Supermax prison — not as an inmate, but to keep one marked man alive long enough to testify. Surrounded by thousands who want his target dead, the only way out is through.
BLOOD COUNTRY
On the run and hunted across the country, Byron Tibor crosses into a Texas border county where one family owns the land, the law, and everyone on it. He's arrested for nothing, by men who've never had to answer for anything. They've spent years deciding who disappears and who doesn't. They've never had a stranger like Byron decide to stay.
