5-STAR REVIEW: UNSTOPPABLE by Michael Maloof

The Description

Kate Preacher: Book 2
Publication Date: March 18, 2025

Betrayal in Paris. Survival in Africa. The world’s deadliest game has a new player.

Former CIA analyst Kate Preacher returns to Paris searching for answers to the terrorist attack that shattered her world—only to find herself in the crosshairs of a sniper who is always one step ahead. Every move she makes is anticipated. Every escape feels temporary. And the deeper she digs, the clearer it becomes that the conspiracy she uncovered is far larger—and closer—than she ever imagined.

When a trusted ally is ambushed and left for dead, Kate realizes she is no longer chasing the enemy.
She is the target.

Her pursuit of the elusive sniper draws her across borders and into Africa’s most dangerous battlegrounds, where warlords, mercenaries, and corrupt powers collide over the fate of a fragile nation. Loyalties shift. Truths fracture. And survival depends on knowing who is lying—before it is too late.

Every enemy hides a secret.
Every ally has an agenda.
Every move Kate makes risks igniting a firestorm that could topple an emerging democracy.

With seconds to spare and a sniper locked on target, Kate faces an impossible choice—risk everything to stop what’s coming or walk away and let a nation fall.

Unstoppable is the pulse-pounding sequel to Relentless—a globe-spanning thriller of betrayal, survival, and high-stakes deception.

This is where Kate learns how far her enemies will go.
And how much it will cost to stop them.

Excerpt The Review

Kate Preacher’s pursuit of justice leads her around the globe as she tracks down the man who killed her husband.

In the sequel to Relentless, author Michael Maloof continued to demonstrate Kate’s vast skill set. Her determination is woven throughout various challenges presented in Unstoppable.

As a former CIA digital forensics analyst, Kate leverages her research skills along with old connections to find answers. It’s a mission packed with danger thanks to allies having their own secret agendas.

The fast pace keeps the adrenaline pumping as Kate navigates one dangerous situation after another. Moving the action from France to Central Africa illustrates a much deeper plot.

Aside from the thriller aspects, Kate’s character also demonstrates vulnerability as she tries to mourn her husband. Her friendship with Isabella shows a more relaxed version until danger threatens both women.

Unstoppable continues to raise the bar in a series driven by a woman seeking answers. Buy Links
