looking, as Garroway liked to think of it, like an enormous black millipede.
They exploded from the open rear ramp, exiting the claustrophobic confines of the AUT and emerging in a vast and partly empty volume of space. The shuttle had backed into the crater burned into the Xul vessel, pushing in through a tangle of what looked like girders or struts and coming to rest in a spider web of twisted beams. Whatever had been in here had largely been reduced to wreckage and debris. Huge masses remained, but so blasted and melted that it was impossible to tell what those masses had been.
At optical wavelengths, the space was in complete darkness, but Garroway’s infrared sensors showed the walls and debris within the hole still glowing in eerie reds and oranges. Some of the wreckage was still molten, in fact, and it looked as though the white-hot plasma from the autie’s thrusters had added to the fiery destruction. Beyond the trapped autie, through the gaping hole in the Xul ship’s side, he could see the stars outside.
“Now that’s what I call a fucking preliminary bombardment!” Chrome yelled over the platoon channel. “Section Two! Follow me!”
They’d sketched out their tactical deployment during the hours of transit as part of the Preble’s cargo. Half of the Marines peeled off and began moving aft within the Xul wreckage, hauling their way through the debris where they had to, using their suit thrusters in open space. Daugherty and Hoyer were with her, hauling two of the nukes.
“Section One!” Garroway called out. “With me!” His suit’s AI oriented him with the forward end of the Xul vessel, painting a targeting cursor on the cavern wall in that direction. He pushed off from a twisted, sullenly glowing girder. On his tactical readout, he saw fifteen of the Marines following him. Lowey, Istook, and Sergeant Ortiz were close behind him, carrying first section’s allotment of nukes. They had a long boost through relatively empty space—almost two hundred meters—to reach the charred and twisted ruin of the cavern’s forward wall. For a long moment, they drifted through empty space. Then, using a much-practiced maneuver, they tucked and twisted, turning so that they were drifting feet-first.
ZGM—Zero-Gravity Maneuvering—was endlessly practiced by Marines assigned to space billets; arguably, that was what distinguished Fleet Marines from the ground-pounders. Garroway’s boots hit the wall, and he allowed himself to crumple with the impact, absorbing the energy in his legs and back to avoid rebounding back into the cavern.
The other Marines came in around him, silently falling into the wall; two, Atkins and Freemont, bounced, drifting back into the cavern, but their buddies grabbed hold of their harnesses before they floated out of reach and hauled them in. Garroway made a mental note to talk to them later about scheduling additional ZGM training.
If there is a later, he reminded himself. So far, the Xuls hadn’t paid any attention to the tiny force of Marines crawling around in the savaged bowels of their ship. But that would change.
“Istook, Ortiz, Lowey,” he said. “Texten up! Engage triggering sequence Alpha. Confirm!”
“Trigger sequence Alpha confirmed,” Ortiz told him.
“Alpha confirmed,” Lowey said.
“Sequence Alpha, confirmed,” Istook added.
Sequence Alpha was controlled by their individual suit AIs. It armed the backpack nukes, setting them to detonate if—and only if—Garroway or Chrome, or Wilkie back on board the autie, or General Garroway back on board the Preble, transmitted a coded radio signal. It was a form of mission insurance. If every member of the boarding party was somehow and suddenly killed, the nukes in their CAS backpacks could still be fired.
Garroway wasn’t sure he entirely trusted Wilkie’s mental thumb on the destruct switch. He hated admitting that to himself, but … there it was. The idea of having a nested set of destruct sequence go/no-go triggers was so that if Chrome and Garroway both bought it in the next few minutes, Wilkie could decide whether or not to trigger the nukes immediately, based on the status of the rest of the assault force. If the AUT was destroyed in the next few moments, and Wilkie with it, the decision would revert to Uncle Clint.
He trusted his uncle. Wilkie, he did not … not entirely. It wasn’t that Garroway thought the guy would push the button on the RST deliberately, but the guy could panic. If he did, he might transmit the firing code before the rest of the Marines could get clear of the Xul vessel, might trigger the nukes even before the autie got clear. That, in fact, was his responsibility if it looked like the mission would otherwise fail.
Cool heads were needed to make that kind of call. And Garroway just wasn’t convinced that the twenty-seven-year-old Wilkie had the prerequisite chill to the organic component of what was stuffed into his skull. He worried too much.
And this wasn’t the time to worry about Wilkie’s worrying. “Lowey!” he said. “Plant your boom-pack here. The rest of you, look for an entrance, some way to get into the ship.”
“Aye, aye, Gunnery Sergeant.”
He helped Lowey fasten the backpack nuke to the cavern wall, using a nano sealant that bonded tighter than any weld. “Okay. Set the timer. Sequence Bravo.”
He watched as he placed his left gauntlet on the pack’s contact plate and fed the Bravo code into the weapon’s computer.
“Charge ‘Whiskey’ is in place,” Garroway announced over the platoon channel. “The clock is running.”
The five nukes had been given the last five letters in the phonetic alphabet—Victor, Whiskey, X-ray, Yankee, and Zulu. The Bravo sequence would detonate the weapon in two hours, unless it received a coded order to revert to Alpha, or to proceed to Charlie.
“Hey, Gunny!” Corporal Hoeffel called. “We got movement!”
Direction was indicated on his tactical feed. Garroway rotated his CAS in space, searching the indicated direction. Yes … there it was.
He wasn’t at first sure of what he was seeing, exactly. It looked as though some of the masses of half-molten metal, the remnants of hull and bulkheads, were growing, with new pieces being extruded from the old. And … he could see a cloud moving past the stars visible through the opening in the hull, like a swarm of gnats or locusts. As he watched, the swarm appeared to solidify in places, filling in gaps and emptiness.
Swiftly, inexorably, the Xul ship was repairing itself.

The HELGA facility, its fire mission against the Xul ship complete, had returned to its original task—tracking and destroying each of the stream of rocks now hurtling in past the orbit of Mars, bound for Earth. Every forty-eight minutes, its recharge was complete, and Kali would loose another brief but deadly stream of invisible fire at another of the distant, fast-moving asteroids. After several shots, HELGA One came on-line as well and began adding its three-second bolts to the ongoing barrage.
HELGA One was directed by a fire-control AI named Durga, after the Hindu mother-goddess destroyer of demons. As soon as she came on-line, Durga began coordinating her fire patterns with Kali, ensuring that two bolts were not loosed toward one target when a single bolt would suffice. There were too many targets, and too little time, for duplication of effort.
Unfortunately, the radar and laser imaging scans that allowed Kali and Durga to identify and target fast-moving rocks light-minutes
