About the book

---

He never wanted to lead. He doesn’t have a choice.

Jason thought the hardest part was behind him. After the death, destruction, chaos, and the danger that defined the Underground’s earlier battles, he had finally found something worth holding onto — security for the people he cared about through collaboration with a powerful ally and the fragile hope of a real future for their nation and their lives. But hope has a way of becoming a target.

Junior MacBain is back — and this time, he has help from the inside.

Jason’s former best friend turned bitter enemy has always been a threat. But when a trusted Underground insider betrays their location directly to Junior, the threat becomes something far more terrifying: inevitable. The Underground is compromised. Their safest haven is exposed. And the clock is already running out as they race against Junior to control the most dangerous weapon the world has ever known.

Now Jason must do the one thing he’s always hated — lead.

Thrust into command of a team he never asked for, on a mission that seems impossible by any measure, Jason has to find a way across the wilderness for his team and go head-to-head with the one enemy who knows exactly how he thinks. Junior MacBain isn’t just powerful. He’s personal. And that makes him the most dangerous opponent Jason has ever faced.

In United, the fourth and final electrifying installment of the Divided Series:

• Explosive action that keeps the pages turning at lightning speed
• Deep, complex characters tested to their absolute limits
• Betrayal, loyalty, and the devastating cost of trust
• A hero forced to rise — even when everything in him says to run

The Underground is broken. The enemy is closing in. Can Jason hold his team together long enough to survive — or will Junior MacBain finally finish what he started?
