HOUSTON - s4story -- Joe Betar announces the release of his debut novel, HAMMER, a gripping, action-packed thriller that blends the raw intensity of elite combat sports with a global story of vengeance, justice, and survival.

In HAMMER, readers meet Jack "Hammer" Garrett—a former UFC world champion who has left behind the brutality of the cage for the quiet solitude of his Texas Hill Country ranch. Believing his fighting days were over, Garrett seeks peace after a storied career. But when a devastating family tragedy shatters his world, that peace is violently ripped away.

The perpetrators made one critical mistake—they didn't finish the job.

What follows is a relentless pursuit across continents, as Garrett uses the same skills that made him a champion—discipline, resilience, and an unbreakable will—to hunt those responsible. His journey uncovers a dangerous web of corruption stretching from cartel strongholds to the corridors of power in Washington, D.C.

What begins as a quest for vengeance quickly escalates into something far more dangerous: a fight for survival against enemies who operate in the shadows and play by no rules.

HAMMER explores what it means to be forged by loss and driven by justice. It is a story where loyalty is earned in blood, trust is scarce, and one man's mission becomes a war he never sought—but was destined to fight.

With sharp pacing, cinematic action, and a compelling anti-hero at its core, Joe Betar's debut establishes him as a bold new voice in the thriller genre.

HAMMER is now available on Amazon: https://a.co/d/0aFupiFF
