Read an Excerpt From SF Technothriller Nucleation

A top-notch VR pilot encounters a disaster during the highest profile space-faring project of her career…

We’re excited to share an excerpt from Kimberly Unger’s debut novel Nucleation—arriving November 13th from Tachyon Publications.

We are live, we are live, we are live…

Helen Vectorovich holds the unique distinction of failing at first contact—and she did it in both virtual reality and outer space.

Only the most elite teams of operators and navigators get to pilot in remote space-mining operations. And no one was better than Helen and her navigator. Together they secured a multibillion contract for establishing an interstellar gate to a distant star. But during a routine mission, what should have been an easy success turned deadly.

Helen, grounded in a desk job, has overeager junior pilots jockeying to take her place, jealous corporate rivals, and nasty rumors blaming her for the botched mission. Meanwhile, Helen’s new discovery in space—the Scale—seems to be…evolving.

When someone—or something—wants to terminate her project, Helen must race to find out why before it is far too late.



The Golfball was reaching the end of its line drive—the hole in one an orbit around an orphan star. No planets depended on that burning ball of resources for life. Nothing would suffer when it launched its payload and started consuming every asteroid within reach. The starship-sized jump-gate would take a year to complete, after which the job of stripping Otlyan23’s asteroid ring of every valuable asset could begin in earnest.

“Mark local time 24:48:16.” The NAV’s voice wasn’t in Helen’s ear, precisely. She didn’t have ears out here. Different bodies took time to get used to, and ears were a luxury item. The vibrations of sound shivered along the walls of the Golfball’s interior and filtered through receivers placed along her spine. “Station live. Station live. Station live.”

“Live and well, Ted. Operator Helen Vectorovich, personal identifier T4T4-957.” She responded automatically, rattling the words and numbers off without thinking. Helen was only the first shift on this year-long project and every shift started this way, every mission, every time. She refocused her vision as Ted worked to unlock the capsule controls from his station in the Fishbowl, a billion miles away. The lights around Helen brightened, moving from hibernation blue to heartbeat yellow. System after system came to life after two years of silent spinning through the black of deep space. From Helen’s perspective through the eyes of the waldo, the room opened up like a cathedral, lights and buckypanels rising around her to a point just over her head. In real-world terms, the whole space was the size of a basketball, but from inside the waldo it was oh, so much bigger than that.

“Okay, Helen, let’s start running the system checks.” In the corner of her vision, a list of tasks popped up, bright enough to be seen, but not so bright that it obscured Helen’s view.

“Starting with hull integrity.” Helen confirmed from memory, rather than consulting the checklist, and was brought up short.

“No, wait.” Ted’s voice rang sharply in her head. “Stick to the new protocol, Helen, personal systems first. If your waldo goes out, this all goes sideways.” The mission checklist filled the right side of her vision, blurring out that side of the room.

“And if the Golfball goes out?” she asked, even though she already knew the answer he’d give. The checklist slid out of view and was replaced by another, much more intimate list.

“We’ll have you in there to fix it.”

“Good thing this waldo works in a vacuum then.” Glib replies were part of the job. Confident chatter was a great defense, not just against the butterflies in your stomach, but against the analysts who would go over your comm chatter line by line if anything went wrong. Helen and Ted both had been through that wringer before; the Ferguson’s Asteroid Incident had made both their careers, but it had also made them much more careful.

Helen turned her attention back to the waldo’s systems. This robot-body wasn’t humanoid so much as arachnoid. Eight legs folded up around a glittering central core of processing power and memory shards. Helen carefully unfolded each pair of legs, noting the fine grey dust that arose from them, and sketched her motions in the air. A quick refocus of the lenses showed her the thousands of tiny corpses, left-behind fragments of the nano-robotic eenies that had assembled the ship and its instrumentation out of interplanetary dust. She grabbed a few still images from the waldo’s memory and sent them through the quantum feed to Ted’s screens.

“Ted, do you see all this dust?”

“Stay focused, Helen. We need you checked out as quickly as possible.”

“Yeah, but check out the pics. Everything should have been used up in construction, I shouldn’t be seeing these eenie shells all over the place.” Everything, from the ship, to the waldo on down to the idiot lights had been built up from a thumb-sized packet of eenies shot through a wormhole the size of a quarter. It was a hugely efficient way to establish a presence around a far-flung system, but it took a long time to build out.

“Everything in order, this is all on record, remember? We’ll look at them when we get to checking out the ship. Protocol, protocol, protocol.”

The waldo couldn’t scowl, but Helen tried it anyway. Waldo Operators like herself were, in a word, interchangeable, as long as there were protocols, lists of instructions to follow. No one pilot got too comfortable with one kind of waldo because you never knew where they were going to put you next.

“Fine.” Helen ran through the checklist, meticulously testing each joint, each actuator, every fiber in the robot body she was remote-piloting. The automatic checks had been run well before she’d been Entangled. These first tests were all about her ability to control the body down to the fingertips. Ninety percent of her jobs were like this, following the list, endless lists that could just as easily be run by an AI, if you asked most people.

Leg eight felt sluggish, Helen felt it before the computer gave her the heads-up. Less than a millisecond slower than its siblings to respond, it took her a little extra focus to get it to match pace with its twin. “Ted, are you getting this? Leg eight?”

“Affirmative. Still inside the workable parameters.”

“Yes, but it still should be a perfect match. This whole rig is professionally built, not extruded by some kids’ crappy apartment printer. It’s not supposed to have that kind of slippage.”

There was a pause before her NAV replied. Entangled communication meant no lag-time, which meant that Ted was considering, or maybe consulting with someone before he replied. “Helen, are you telling me you cannot work within these tolerances?”

“No, I’m handing you the opportunity to wring a mea-culpa payment out of whatever contractor slipped a decimal point.” Smartass was the only response that played well. Too many complaints got you written up. Keep the NAVs laughing and they might not take every comment seriously enough to notate. Piss a NAV off and you’d hang yourself with the rope they’d given you.

Except Ted. She’d been partnered with Ted long enough to know he wasn’t about to write her up for being particular. Helen handled the hardware, Ted handled the management. Between the two of them they’d managed to stay one of Far Reaches’ top operations teams for the past year. A position that made high-profile gigs like running the Golfball much easier to get assigned to.

Ted’s snort reverberated in her head. “Good luck collecting on that… it’s all code by committee these days, you know that.”

“Team-based engineering provides better results,” she quoted, tossing a line from one of their training manuals back at him. In the years since they’d arrived at Far Reaches, they’d found their rhythm working within a structured system, but Ted’s rebellious streak was always looking for an opportunity to complain. Three years ago, the Ferguson’s Asteroid Incident had made them an inseparable team, which meant covering for each other’s personality quirks. Ted handled the people, Helen handled the hardware.

“Committees aren’t teams, Helen. In fact, they’re the opposite of teams.” She could hear his voice change, the words spoken so the rest of the team back at Flight Ops could hear him.

Ted never could resist an audience.

The items on the task list turned green one by one as Helen worked her way down the line.

“Are you seeing the bad sensor on memory shard three?” he asked.

“Yep.” Helen stretched out an arm and popped a claw-tipped manipulator out to give the shard in question a tap. The numbers on her screen shifted, running up and down as it shifted in the socket. “It’s just loose, hold on.”


“I’m deploying point-one-one picoliters of mix M37 at the base to re-seat the shard.” Helen rattled off the specifics so Ted could add them to the mission report. The blue gel, loaded with specialized eenies, filled the empty gaps in the socket and started to harden immediately. “Can you run the diagnostic?”

The eenies were too small to hold their own programming. They would pick up on the instructions Ted broadcast through the NAV computer and repair the chip’s base to match the specs. As long as he sent the right programming streaming over the air, everything would go smoothly.

“It’s not supposed to be loose, Helen.”

“Congratulations, that makes two, count ’em, TWO mea-culpas on one job. Company record is five, Ted, are we going for the record on this trip?” Helen was settling into the waldo properly now; dispensing the repair mites had been as simple as drumming a fingertip on a dashboard. It was telling, the things that Ted worried about. As long as she’d known him, his focus had been on the people, the reports, what to say and how to say it—he was the medium between the managers and the waldo-jockeys like Helen.

The memory shard came back online, joining the twenty others now jostling for her attention. Helen put them out of her mind for now, focusing on getting the checklist out of the way so they could get on with the fun stuff.

“Are you seeing the readings from array two?”

“Array two? Ted, we’ve still got to finish this bit here.”

“I’m breaking protocol.” Something in his tone of voice shifted, a note of panic that shouldn’t have been there. “NAV override one-five-five.”

Helen felt the locks release and her waldo was free, unrestricted. It was amazing. It was totally off book. She didn’t dare move a finger, or a claw. “Ted, what’s up?”

“Remember how we were just talking about how you could fix the Golfball?”

Oh shit.

“You’re going to have to fix the Golfball.”

“Oh sh…” She cut the words off before they could be recorded. “Okay. How bad?”

“Bad. Bad enough where I just put in a call to Ivester and XERMo, so let’s get on this. I want something to tell them when he logs in.”

“Okay, what broke and where do I start?” Helen waited for Ted to throw the appropriate checklist into her line of sight. She counted to two… then three…


“Ted? Do we have a protocol? There is a plan for this, right?” She could feel her heart rate quicken. A billion miles away, trapped in her coffin, her palms began to sweat.

“Working on it.” Two or three lists popped up as Ted cycled through, one after the other, all with names like “Catastrophic hull failure” and “Venting acidic atmosphere breaches.”

“Ted, can we run something with ‘Catastrophic’ in the title? It’ll make me sound more like a badass.” It was meant to be funny, to take the edge off her own worry. What was supposed to be a high-end, high-priced milk run was starting to turn into the kind of situation that could end with her driving moles for the remainder of her career. Ted wasn’t listening and the joke fell flat.

The lists settled down and Helen was faced with a number. No title, no designations, just a number, 9523. After each step was listed a single word. Evaluate. It was a slow list. Test and assess, test and assess. It wasn’t Ted’s usual efficient task-making. It was a list full of fear.

“This is it?” She didn’t need to ask, but she did, just to be on record. Even when they were crèche-kids, Ted never operated from a point of fear. The caution alone told her just how bad the situation was.

“So far. See where it says ‘Evaluate’? Those are our riff-points. That’s where we get to make stuff up if we need to. Just make sure you verbally justify each and every decision before you take action so we have it all documented.” They were moving into unfamiliar territory now. A small part, a very small part of Helen’s brain wished they could just go back to following the original boring checklist.

“Roger that. First on the list, checking hull integrity.”

This time around, Ted didn’t interrupt. Helen opened a connection from her waldo to the bank of glittering shards that comprised the Golfball’s processing core. It was much like watching a video, she could see the data coming in, but at this level she couldn’t interact with it, that was all on Ted. The waldo and the Golfball were isolated from one another, two completely separate entities, down to the eenies that built them. Any connection between them had to be made manually.

“Ted, are you seeing this?” The numbers never lied, it was Helen’s most and least favorite thing about them.


“It’s like the hull never got finished.”

“Just the facts please, we don’t do theories.”

“I’m the one running the waldo, I get to theorize. Especially since I’m going to be making the repairs.” The visualization of the outside of the Golfball appeared in her line of sight. “The reason you’re not getting any data from sectors two through six is there are no sectors two through six.” She spun the image, noting where the green lines crossed into red as numbers came and went.

“What? Why?” That note of panic was back, more than a note, an aria of panic that Ted’s voice wasn’t qualified to sing.

“There’s no signal coming back, no power going in. It’s gotta be something simple, maybe the eenies just didn’t get initialized properly?”

In the corner of her vision she could see the mirror image of Ted’s console displayed in outline. Ports opened and closed as he dug deeper into the Golfball’s programming than Helen was allowed to go. Helen did her own digging, accessing the layout of the Golfball to see if she could get a better read on the outer hull.

The hissing sound broke her concentration.

“Ted, are you whistling?”

“Am I what?”

“Shut up a second, I hear something.” It was a high-pitched sound, tickling the same place in her brain that a dentist’s drill did, making the muscles along her spine twitch.
