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 land in the crosshairs of a sniper who’s always one step ahead. As the conspiracy unravels, Kate is pulled into a plot far bigger than she imagined—and hunted by an enemy closer than she thinks.
When a trusted ally is ambushed and left for dead, Kate realizes she’s closing in on her target—but she’s also next on the list. Her pursuit of this deadly phantom takes her across borders and into Africa’s most dangerous battlegrounds, where warlords, mercenaries, and corrupt powers collide over the fate of a nation.
Every enemy hides a secret. Every ally has an agenda. Every move Kate makes risks igniting a firestorm that could topple a fragile government.
With seconds to spare and a sniper locked on target, Kate must make one final move—risk everything or watch an emerging democracy crumble.
Unstoppable, the pulse-pounding sequel to Relentless, is a rollercoaster of suspense, heart-stopping action, and jaw-dropping twists. With smart, fearless characters, high-stakes conflict, and emotional depth, Kate Preacher’s journey will keep you riveted until the final shocking conclusion.
