Some cases are just cases. This one is personal.

When a bomb tears through a Midtown Manhattan parking garage on a Tuesday night, NYPD Detective Marcus Kane catches what looks like an act of domestic terrorism. When a second device surfaces two hours later — different construction, same cold calculation — Kane understands that this isn't a single attack. It's a beginning.

A shadowy group calling itself The Remnant has spent two years in hiding, building toward a reckoning they've promised the world isn't ready for. They have a manifesto, a network, and enough stolen military-grade material to make good on every word of it.

Kane and his partner, former Army bomb disposal specialist Officer Dana Reyes, follow the trail from the streets of New York City to the frozen landscape of rural Montana — where a quiet small town has been weaponized, and something far more dangerous than anyone imagined waits beneath its surface.

But the deeper Kane goes, the more the case stops feeling like an investigation and starts feeling like a reckoning of his own.

Because the man running the operation from a fortified bunker beneath a Montana hillside isn't a stranger.

He's Kane's brother. And he's been building toward this for twenty-five years.

True Believers is a gripping, emotionally charged thriller about conviction, family secrets, and the devastating cost of beliefs taken too far. With two cities on a countdown clock and a truth that cuts closer to home than any case ever has, Kane must stop a conspiracy — and decide what remains of the brother he lost long before any of this began.

Some true believers finish what they start. Kane intends to make sure his brother doesn't.
