I TOOK A BULLET meant for a young Marine and lost my leg saving him. The next day his whole battalion showed up at my house. Marines don't move like that for a thank-you. What were they carrying?

Forty-eight hours after Admiral Mercer's arrest, the fallout swept through the United States Department of the Navy like a wildfire.

With the evidence unlocked from Box 412 and Mercer's recorded confession, federal agents launched coordinated raids across four states. But one target remained at large: Senior Chief Ronald Hayes—the man who had placed the IED order and executed David Vance six years ago.

"Hayes was spotted two hours ago at an abandoned naval supply depot near Chesapeake," Captain Vance reported, standing in the tactical command center set up inside my living room. "He's heavily armed, and he has two former Apex mercenaries with him. They're preparing to board a private cargo boat heading toward South America."

I looked down at my prosthetic leg, which was now fitted securely back onto my stump. The physical therapy had been brutal over the last three months, but the fire inside my chest gave me a strength I hadn't felt since the convoy explosion.

"I'm going with you," I said, standing up from my wheelchair and leaning on my cane.

"Sarah, no," Eli said, stepping forward from the kitchen counter where he was wrapping his bruised hand in fresh gauze. "You're still recovering. You don't have to face him."

"Hayes took my husband, Eli," I said, turning to look him dead in the eye. "He took my leg, and he tried to take your freedom. I am a Navy corpsman. My place is with my Marines."

Captain Vance looked at me for a long moment, then nodded slowly. "She comes. But she stays in the tactical command vehicle with the medical team."

Thirty minutes later, three blacked-out tactical vans sped down the dark, pine-bordered highway toward the Chesapeake waterfront.

The supply depot was a sprawling, rusted steel warehouse surrounded by chain-link fencing and decaying concrete piers. The sound of waves crashing against the wooden pylons mixed with the low rumble of a cargo boat's diesel engine idling at the dock.

"Thermal imaging shows three hostiles inside the main office building," Sergeant Cruz announced, checking his monitor inside the command van. "One target matching Hayes's profile is moving toward the gangplank with two heavy aluminum cases."

"Move in," Captain Vance ordered into his radio headset. "Non-lethal containment if possible, lethal force authorized if threatened."

The Marines breached the perimeter fence with silent wire cutters, moving across the tarmac in two tactical teams.

Suddenly, a heavy heavy-caliber rifle shot rang out from the warehouse roof.

BOOM!

A Marine near the front gate fell to the concrete, clutching his thigh.

"SNIPER ON THE ROOF!" Cruz yelled over the comms. "MAN DOWN! IT'S CORPORAL MILLER!"

My instincts took over instantly. Before Vance could stop me, I grabbed my medical kit, threw open the rear doors of the command van, and moved across the gravel lot as fast as my prosthetic leg could carry me.

"Sarah! Stay back!" Vance shouted over his radio.

Bullets sparked against the rusted shipping containers around me, but I didn't stop. I dropped to my knees beside Corporal Miller, pulling my tourniquet from my medical vest and securing it tightly above his thigh wound.

"Hold steady, Marine," I said, my voice calm and firm as I packed the wound with quick-clot gauze. "You're going to be fine."

High above us on the roof, Senior Chief Hayes stood near the railing, holding an assault rifle, his face lit up by the tactical lights of the approaching police cruisers.

"Miller!" Hayes roared down at me, his voice wild with unhinged panic. "You should have stayed in your wheelchair!"

"You should have stayed in Coronado, Hayes!" I shouted back, holding my ground beside the wounded Marine.

Before Hayes could raise his rifle again, Eli Mercer sprinted onto the warehouse roof behind him. Eli didn't have a rifle—he carried a heavy metal breach bar. With a roar of pure fury, Eli slammed the iron bar into Hayes's rifle, shattering the wooden stock and knocking the weapon off the roof into the ocean below.

Hayes spun around, drawing a combat knife and lunging at Eli.

The two men crashed onto the rusted roof tin, rolling near the edge. Hayes managed to pin Eli down, pressing the steel blade toward Eli's neck.

"Your father was a coward, Mercer!" Hayes snarled, his breath hot against Eli's face. "And you're going to die just like David Vance did!"

"Not today," a voice echoed across the roof.

Captain Vance stepped out from the stairwell tower, his sidearm raised, aiming directly at Hayes's head. "Drop the knife, Senior Chief. It's over."

Hayes looked at Vance, then down at Eli, then out at the ten police cruisers filling the parking lot below.

With a bitter scream of defeat, Hayes dropped the knife, raising his hands into the air as Sergeant Cruz tackled him to the roof deck and snapped steel handcuffs around his wrists.

I finished bandaging Corporal Miller's leg as the paramedics arrived to load him onto a gurney.

Eli walked down the exterior metal stairs, his face covered in sweat and soot, his hands shaking slightly as he reached the bottom step.

He looked at me, then at the ambulance lights flashing against the dark sky.
