Holden gestured at his screen. “Nothing new. It doesn’t look like they’ve noticed us yet.”
“Their reactors are still down?”
“The heat signature’s just sitting there.”
Bobbie pressed her lips together and nodded. “That’s not going to last much longer.”
“We could shoot ’em,” Amos said. “It ain’t my call, but in my experience the guy that throws the first punch usually wins.”
“Show me the estimated range,” Bobbie said. Holden pulled up the passive sensor array. At roughly five million klicks out, the Azure Dragon was about ten times as far from them as Luna was from Earth. It probably wouldn’t crew more than a dozen people. In the infinite star field, it would have been invisible to the naked eye. Even if the enemy had been on a full burn, the exhaust plume would have only been one point of light among billions. “How accurate is that?”
“I’m not sure,” Holden said. “Normally we’d be using ladar.”
“Give it ten percent either way,” Naomi said. “At this range and scale, passive sampling errors expand pretty fast.”
“But with the ladar?” Bobbie asked.
“Within a meter,” Naomi said.
“You ever think about how much ammo’s flying around out there?” Amos said, reaching up to brush the floor with outstretched fingers. The contact started him drifting almost imperceptibly toward the ceiling and at the same time rotating back toward consensus upright. “Figure all those PDC rounds that didn’t actually hit something; most of the rail-gun rounds, whether they went through a ship or not. All out there someplace going at the same speed as when they left the barrel.”
“If we shoot them, they’ll still look for who did it,” Naomi said.
“Might not,” Amos said.
Naomi looked at Bobbie. “We’re going to have to start a braking burn soon or we’ll skin right past them.”
“How long?” Bobbie asked.
“Three hours,” Naomi said. “Anything more than that, and we’ll need to go on the juice or risk the deceleration g popping a bunch of blood vessels we’d rather keep whole.”
Bobbie tapped the tips of her right middle finger and thumb together in a rapid stutter. When she nodded, it was more to herself than to them. “Screw this. I’m tired of waiting. I’ll go wake Alex up. Let’s get it over with.”
“All right, boys and girls,” Alex drawled. “Everybody strapped in and ready?”
“Check,” Holden said on the open channel, and then listened as the others reported in. Including Clarissa Mao. It was an illusion built from anticipation, but Holden felt like the lights were a little brighter, as if after weeks in dock, the Roci was excited to be doing something important too.
“Reactor’s good,” Amos reported from the machine deck.
Alex cleared his throat. “All right. We’re good to go in ten … nine …”
“She’s seen us,” Naomi said. “I’ve got action from her maneuvering thrusters.”
“Fine, then. Three-two-one,” Alex said, and Holden fell back into his crash couch hard. The gel pressed in around him, and the ship rumbled the deep bass of the drive as it spilled off speed. To the Azure Dragon, it would be like a bright new star had appeared. A supernova light-years away. Or something less dangerous but much, much closer.
“Ladar’s up,” Naomi said. “And … I’ve got lock.”
“Is their reactor up?” Holden asked, at the same time that Bobbie said, “Give me fire control.”
Naomi answered both. “Their drive’s cycling up. We probably have half a minute. You have control, Bobbie.”
“Holden,” Bobbie snapped, “please ring the doorbell. Alex, surrender maneuvering to fire control.”
“Done,” Alex said.
Holden switched on the tightbeam. The Roci found a lock at once. “Azure Dragon, this is the Rocinante. You may have heard of us. We are on approach. Surrender—”
Thrust gravity cut out and their crash couches hissed as the ship spun on two axes.
“Surrender at once and prepare for boarding.”
Naomi’s voice was calm and focused. “Enemy reactor is coming up.”
The ship seemed to trip, throwing Holden and Naomi up against their straps. The keel-mounted rail gun pushed the whole ship backward in a solid mathematical relationship to the mass of the two-kilo tungsten round moving at a measurable fraction of c. Newton’s third law expressed as violence. Holden’s gut knotted and he tried to lean forward. The long seconds dragged.
Naomi made a small, satisfied sound in the back of her throat. “Okay, their reactor’s shutting down. They’re dumping core. We’re not seeing nitrogen in the plume. I don’t think they’ve lost air.”
“Nice shooting,” Amos said on the open channel.
“God damn,” Bobbie said as the Roci shifted back. “I have missed the hell out of this.”
Thrust gravity returned, pushing Holden back as they slowed toward the drifting science ship. It was harder now—a solid two g he could feel in his jaw and the base of his skull.
“Please respond, Azure Dragon, or we’ll shoot you some more,” he said.
“This doesn’t feel right,” Naomi said.
“They started it,” Alex said from above them in the pilot’s deck. “Every rock that dropped, they had a part in.”
Holden wasn’t sure that was what she’d meant, but Naomi didn’t press it, so maybe it had been. “Not getting any response, Bobbie,” he said. “How do you want to play it?”
In answer, the former Martian marine climbed down from the gunner’s station, hand over hand in the high gravity. The muscles in her arms were like cords of wire, and her grimace said both that the sheer effort hurt and that she kind of liked it. “Let them know that if they open up on us, they won’t get crash couches on the way to jail,” she said, passing down toward the airlock. “I’m just going to slip into something more comfortable.”
The crash couches shifted a little as Alex bent their trajectory so they wouldn’t melt the Azure Dragon to slag in their drive plume. Bobbie grunted and took a new grip on the handholds.
“You know there’s a lift, right?” Holden said.
“Where’s the fun in that?” Bobbie said as she sank out of sight.
Naomi shifted against the high gravity so that he could see her face. Her smile was complex—discomfort and pleasure and something that looked like foreboding. “So that’s what she looks like when she takes herself off the leash.”
Shedding the last of their velocity and matching orbit wasn’t fast. Holden listened with half an ear while Alex, Amos, and Naomi coordinated with the Roci’s systems to bring them alongside. Bobbie chimed in now and again when she wasn’t putting her powered armor together and running through its system checks. The greater part of his attention stayed on the enemy. The Azure Dragon floated in silence. An expanding cloud of radioactive gas that had been its fusion core slowly dissipated behind it until it was hardly denser than the surrounding vacuum. No emergency beacon. No announcement of defiance or surrender. No response to his pings and queries. The silence was creepy.
“I don’t think we killed them,” Holden said. “We probably didn’t kill them, did we?”
“Doesn’t seem likely,” Naomi said, “but I suppose we’ll find out. Worst case, we did, and it still makes it easier to keep the rocks from dropping on Earth.”
Something in the tone of her voice caught him. Her eyes were on her monitor, but she didn’t seem focused. Her mind a million kilometers away.
“Are you all right?”
Naomi blinked, shook her head like she was trying to clear it, and put on a smile that was only a little bit forced. “It’s just strange being out here again. And I can’t help wondering whether I know anyone on that ship. It’s not something I thought about much before.”
“Things have changed,” Holden said.
