To become a biker was my terminally ill son's ultimate dream. I had no clue what was coming when a tattooed doctor I doubted secretly whispered to him.

The roar of the single-cylinder Husqvarna 701 Enduro tore through the midnight tempest like a chainsaw through sheet metal.

Silas rode into the teeth of the gale. The rain wasn't falling—it was flying horizontally, driven by fifty-mile-an-hour gusts that threatened to rip the handlebars from his grip. His knobby tires fought for traction in the red clay slurry of the abandoned logging trail, kicking up roosts of mud ten feet into the black sky.

Every jolt over the exposed granite boulders sent a white-hot spike of agony through his shattered right femur. But Silas didn't slow down. In his mind, he wasn't looking at the dark, lethal precipice dropping off three hundred feet to his right.

He was looking at Toby’s little bald head. He was looking at Marcus, the combat medic who had dragged him out of a burning Humvee in the Korengal Valley twenty years ago, refusing to let him die when the army doctors said he was a lost cause.

*Repay the debt,* Silas repeated to himself like a mantra over the screaming roar of the engine. *Repay the debt.*

Back at the compound, the battle was entering its most desperate phase.

Toby's heart rate had surged to an impossible 198 beats per minute. The boy was no longer thrashing; he had slipped into an ominous, flaccid coma. His lungs were filling with fluid, crackling like dry autumn leaves every time Eleanor squeezed the ambu-bag.

"His pupils are sluggish," Eleanor said, shining a penlight into Toby's glassy eyes. "Marcus, the cerebral edema is setting in. If we don't drop his intracranial pressure right now, he will suffer irreversible brain death in thirty minutes."

"Mannitol," Marcus ordered, his hands flying across the medical supply table. "We push a hundred milliliters of twenty percent Mannitol to draw the fluid out of his brain tissue. Sarah, get more ice! Pack his neck! We have to protect his brainstem!"

Sarah bolted to the ice machine, scooping freezing slush into heavy plastic bags with her bare, bleeding hands. She didn't feel the cold. She didn't feel the skin tearing on her fingers. She was a mother operating on pure, distilled adrenaline.

She sprinted back into the cleanroom, dumping the ice around Toby’s burning skull.

"Toby, listen to my voice," Sarah wept, leaning down until her lips were pressed against his ear. "Don't you dare let go. Silas is on the road. The medicine is coming. You're a biker now, baby. You're Little Bones. You have to ride this out!"

Suddenly, the compound’s perimeter alarm began to wail—a harsh, rhythmic klaxon that echoed through the vast metal hangar.

Bear's voice crackled over the workshop intercom: *"Marcus! We got company! State Police and county sheriffs. Six cruisers just breached the outer gate! They have an arrest warrant and an emergency custody extraction order from Judge Vance's court!"*

Marcus didn't even look up from Toby's chest. "Hold the line, Bear! Don't let them into this hangar!"

Outside, through the sheets of rain, six police cruisers skidded to a halt on the gravel apron, their blue and red strobes painting the wet pines in flashes of violent neon.

A dozen armed officers stepped out into the mud, shotguns and sidearms drawn. Leading them was none other than Dr. Arthur Sterling, huddled beneath a massive black umbrella, accompanied by the County Sheriff.

"Dr. Vance!" the Sheriff’s voice boomed through a cruiser's PA system. "This is Sheriff Lawson! You are surrounded! You are harboring a kidnapped minor and in possession of stolen schedule-one biomedical materials! Power down the facility and step out with your hands up!"

Twenty Ghost Prophets stepped out from the shadows of the hangar overhang.

They didn't draw guns. They didn't shout. They simply stood shoulder-to-shoulder across the massive sliding steel doors of the hangar—a wall of black leather, tattooed arms, and cold, unflinching defiance.

Bear stepped forward, chewing on an unlit cigar, his heavy wrench resting loosely in his right fist.

"Sheriff," Bear called out, his voice easily carrying over the rain. "The boy is in the middle of a life-saving medical procedure. You take one step toward those doors, and we will consider it an imminent threat to a human life."

"You're obstructing justice, Bear!" the Sheriff yelled. "Step aside or we will use lethal force!"

Inside, Eleanor looked at Marcus. "They’re going to breach. If they kick those doors open, the dust and contaminants will kill Toby instantly. His immune system has zero white cells left."

Marcus grabbed an emergency syringe filled with Mannitol, slammed it into Toby's IV line, and looked toward the back of the hangar.

"They won't breach," Marcus said grimly.

"Why?" Sarah cried. "They have guns, Marcus!"
