Welcome to The Sentinel Universe

What happens when the justice system you’ve spent your life defending can no longer deliver justice?

For Tia Jackson, the answer begins with grief, rage, and a supernatural calling she never asked for.

By day, Tia is a criminal defense attorney navigating the corrupt institutions of Metronix City. By night, she becomes The Sentinel—a divinely empowered vigilante chosen by Oya to stand at the crossroads between justice and vengeance.

But Tia’s story is bigger than one woman with supernatural powers.

The Sentinel Universe is filled with corrupt judges, criminal syndicates, dangerous technology, ancient supernatural forces, complicated relationships, hidden histories, and a city where justice is constantly being bought, sold, manipulated, and fought for.

Is The Sentinel Universe for You?

Enter the world of The Sentinel if you enjoy:

  • Powerful Black female superheroes
  • Vigilante justice and morally complicated choices
  • Yoruba mythology and supernatural power
  • Corrupt systems, crime, and urban fantasy
  • Grief and rage transformed into power

If you’re drawn to Batman’s gritty urban vigilantism, Storm’s elemental power, and the morally complicated justice of Watchmen, The Sentinel Superhero Vigilante Series brings those touchstones into a Black woman-centered world of Yoruba mythology, supernatural crime, and systemic corruption.
