CHAPTER 1
Denver International Airport
Late morning
Harvey “Ben” Bennett’s ribs reminded him of every hard edge between Puerto Rico and Colorado. Airplane armrests. Bulkhead walls. A steel ladder on a cartel pier. All of it had left signatures in purple and yellow under his shirt.
He’d had little sleep since their last foray, but part of that was self-inflicted. Reggie and Sarah had forced them all to relax for two days after the incident in Culebra, off the coast of Puerto Rico. It was well-needed, but he’d hoped to relax at home, with his family.
His stomach tightened. The only food he’d had was something beige that claimed to be chicken, eaten in a hurry on the flight from Atlanta to Denver. He wanted a hot shower, a wood-burning stove, and his wife’s brisket — at home in the Chugach Mountains, in the log-and-satcom Frankenstein they called CSO HQ.
Gareth “Reggie” Red clomped off the jet bridge behind him, humming the same salsa riff that had infected them at a roadside cantina outside Ponce. His Hawaiian shirt, a ripped, crime-scene-stained atrocity, fluttered like a defeated flag. A sweat-bleached cap sat backward on his head. One eyebrow sported butterfly tape. Somehow he still looked relaxed.
“Next vacation,” Reggie said, weaving through a cluster of ski families, “no jungles, no smugglers, no boats shaped like bullets. We fly home, you grill moose steaks, we drink every IPA in Anchorage, and I don’t get tetanus from a dock spike. Deal?”
“Julie promised brisket,” Ben said. “Moose is Plan B. And you’re current on your shots.”
“Yeah? Pretty sure cartel coral counts as a new disease vector.”
They spilled into the main concourse. Neon-lit chains. Kids dragging dinosaur-shaped roller bags. A businessman shouting into earbuds about quarterly burn rates. Ben’s body wanted to fold into the nearest chair. His brain was already halfway to Alaska — wood smoke, cold stars, Hope’s tiny boots left by the door.
Their cabin sat on a bench above Turnagain Arm, solar panels angled like black wings. One wing of the place was just… cabin: kitchen, loft, crib. The other wing was cables, racks, screens, generators, encrypted sat uplinks, and three shipping containers stitched together into the headquarters of Civilian Special Operations — their operation, their rules.
When government agencies hit walls, they called the CSO. When the CSO hit a wall, Julie usually cut a hole through it.
His phone came alive the second airplane mode dropped. Fifteen messages stacked up; three were tagged CSO-secure. Two were from Anchorage neighbors complaining about a moose licking their diesel tanks again. Nine were from Julie — timestamps all across his flights.
He opened the thread.
Wheels down yet?
Hope tried to feed the dog dryer lint. Save us.
Brisket stalled at 185°. Smells ridiculous.
Ping me when you hit the gate. Need you.
Delete that. Need you home.
…Ben?
He smiled — then frowned. The later texts had attachments. Data packets. Raw telemetry headers. She was working.
He thumbed the call button.
She picked up in half a ring. The background noise consisted of low fan hum, distant beeps from monitoring gear, faint baby chatter.
Home.
“Tell me you’re in the truck,” she said. No hello. Pure Julie — warm wrapped around purpose.
“Still at the gate,” Ben said. “Ready for our last leg, so we’re still hours out. My body’s present, but a little beat up. Reggie’s currently arguing with gravity.”
“Put gravity on hold.” Her chair squeaked; he pictured her in the ops annex, three monitors up, one eye on Hope’s playpen cam, one on inbound sensor feeds. “We’ve got a problem.”
He slowed without meaning to. A man behind him rammed a luggage cart into his calf and apologized. Ben waved him past. “If the problem starts with ‘tractor won’t start’ and ends with ‘moose ate solar wiring,’ I’m still coming home.”
“I wish,” she said. “This is a flag from a geographic area we’re both familiar with. Yellowstone National Park.”
Cold slid under his bruises. “You can’t be serious.”
CHAPTER 2
“I’m staring at thermal anomalies and a series of seismic pulses the park never published. Somebody’s drilling inside the caldera. Not shallow prospect holes — hot bore signatures. They spoofed the public feeds. My old CDC credentials still open a back door on a USGS mirror. That’s how I saw it.”
Reggie, eavesdropping, made a cartoon gagging sound. “Yellowstone again? I thought you swore a blood oath to never go there again.”
Julie heard him and snorted. “Hi, Reggie. You still alive?”
“Barely,” he said. His voice grew serious. “Are there spores?”
“No, not that kind,” she said. “For better or worse, this isn’t the same thing we dealt with before. This smells like geo-engineering. Private. Heavy power draw. Unauthorized.”
Ben threaded through a food court and dropped onto a bench under an ad for ski boots. “Walk me in. Start at why you were looking.”
“You know how I still subscribe to the emergency pathogen feed for the Interior West?”
Ben rolled his eyes. Nerd.
“A CDC buddy in Bozeman pinged me last night — unexplained heat upticks in outflow gas near Norris Geyser Basin. Nothing huge, but off seasonal baselines. Could’ve been instrument drift. Then three more stations flickered — heat plus helium anomalies.”
“Helium,” Ben said. “As in…?”
“Yep. The gas we use in party balloons,” she said. “Isotopic ratios spiking. Crustal helium is degassing faster than usual. That can happen before magma migration. Or… when you drill holes where you shouldn’t.”
He scrubbed a hand across his face. Memories slammed in: the smell of sulfur and pine; the hiss of ruptured lab tanks; Julie in a Tyvek suit lit by red hazard lights; his ranger badge clipped sideways as they ran through steam running from an outbreak they weren’t even close to understanding. It had nearly turned Yellowstone — and the rest of the continental United States — into a bioweapon carnival.
They’d survived, fallen in love, built a life, a kid, a private black-box response unit. And promised each other: never again with that park unless the world needed saving.
“What do the feds say?” he asked.
“The official USGS public board shows routine background. Because the real data never hit it. Someone intercepted.” Her voice flattened. “I scraped the packet headers before the gap closed. IP points to a contractor shell in Houston. Drill logs embedded in metadata show depths you don’t hit unless you’re either stupid or reckless. Or both.”
“Someone wants helium?”
“Helium-3, probably,” she said. “At least, that’s my best guess. Hartmann Energy’s been pushing speculative Helium-3 extraction papers. They talked about closed-loop thermal exchange above melt zones. That tech doesn’t exist — on paper. But if they’re trialing field gear…”
Reggie leaned close to the phone. “Helium-3’s for fusion, right? Like free energy? Clean reactors. Unicorn dust, basically.”
“Right,” Julie said. “There’s some data suggesting it’s worth pursuing, though. But if you mis-model pressure rebalancing in a magma reservoir and start bleeding gases and radiant heat? You could destabilize hydrothermal caps. Trigger phreatic blasts. Worst case, cascade pressures upward. Yellowstone’s plumbing is touchy.”
“Define worst case,” Ben said.
“Boiling Wyoming,” she said. “And downwind… ash across most of North America. I know you can’t sleep on planes, but I need you to stay awake a little longer.”
He looked at the crowds — vacationers grabbing coffee, kids chasing baggage carts — and felt the gap between their world and his widen. “You’re asking me to skip my connection to Anchorage and catch the next ride to the world’s largest powder keg.”
“I’m not asking,” she said softly. “We are the CSO. Our crew. Our rules. When agencies need quiet help, they call us. When Yellowstone pings and half the data disappears, I call you.”
He shut his eyes. “What’s the window?”
“Short,” she said. “I’ve got a charter rotor at Centennial Airfield holding fuel. Pilot owes us a favor. She can take you to a forward strip outside West Yellowstone. From there, you meet Nia Talbot — ex-park ranger, now geophysicist under contract to a geothermal outfit that just got cut out of a project. She’ll guide you in.”
“Nia,” Ben said, dredging the name. “She was seasonal law enforcement the summer after the virus mess. Didn’t talk much. Saw her break a poacher’s wrist, though, when he tried to lay a hand on her. That was pretty cool.”
“That’s her,” Julie said. “She’s angry. Use that.”
Reg gie made a face. “We’re going in under whose flag? Ours? Park Service?”
“Ours,” Julie answered. “‘Unofficial liaison.’ If the Park asks, you’re support consultants evaluating infrastructure sabotage. Keep it gray. Keep it quiet until we know whether Hartmann — or whoever — has a legal permit they buried under red tape.”
Ben rubbed the back of his neck. “And Hope?”
Julie laughed softly. “Napping. She dumped crackers into the server rack and shorted a keyboard, so I’m running ops on a backup laptop. The dog is furious about moose tracks near the generator. Life continues.”
Guilt twisted, especially since he’d been the one to push the ‘let’s get a dog, it’ll be great’ narrative at home, but he’d had little time to actually interact with the thing. “I told you I’d be home.”
“You will,” she said. “Come fix the moose fence when you get back. Also, I called and had the hotel staff put a sealed bottle of Talkeetna rye in your duffel at the hotel in San Juan right before you checked out. Complete the mission, claim the bottle.”
Reggie clapped. “Marry me, Julie.”
Ben frowned.
“Spoken for,” she said. “And so are you. Sarah’s home safe, and I think she’s flying up here in a couple of days to help out with Hope. And, of course, to provide moral support for you two.”
Ben laughed. Sarah was Reggie’s long-term girlfriend and CSO expert in anthropology and archaeology. They leaned on her expertise quite a bit, especially lately, as she had been teaching at a small conference in Puerto Rico while Ben and Reggie had been there.
“And Ben?” Julie asked.
“Yeah.”
“Don’t let history repeat itself.”
He nodded even though she couldn’t see. “Copy.”
She hung up.
For a few beats the airport’s roar filled his ears — rollers on tile, boarding calls, espresso steam. He stared at a sign for ski shuttles until letters blurred.
Yellowstone. Again.
He tried to ignore the phantom tang of sulfur in his throat.
Reggie sat beside him, elbows on knees. “We could say no.”
“We could,” Ben said.
“But we won’t.”
“Nope.”
They stood. Baggage claim waited below. So did rental cars, a long haul to Centennial, and a flight toward the caldera that had changed his life.
CHAPTER 3
They hit the escalator down. Baggage claim spun to life before they reached it. Skis clattered; kennels rolled; a child slapped the moving belt and laughed. Ben’s duffel came out first — olive drab, duct-taped. Reggie’s came second and thudded like contraband. He snagged both.
Outside, wind bit — Front Range cold, dry and sharp. Snow rimmed the medians, gray where plows had piled it. Ben unlocked a mud-brown SUV from a rental row; Reggie dumped gear in back and climbed in, cracking his knuckles.
“Map says ninety minutes to Centennial if traffic behaves,” Reggie said, buckling in. “Less if we break laws.”
“Break laws,” Ben said, pulling onto Peña Boulevard. “We’ve got a volcano appointment.”
He merged south. Denver shouldered up on the horizon, glass and steel under winter sun. Reggie fished a duty-free-store bag from between his boots and held up a six-pack. “Liquid carb load. Pilot-prep.”
“Fantastic.”
They rode in silence through Aurora sprawl, past snow-dusted rooftops and billboards for elk jerky. Ben toggled his phone to the CSO encrypted client. Files from Julie cascaded in: raw seismographs, thermal overlays, helium ratios annotated in red. One frame stopped him cold — a time-sequenced heat plume punching through the snowpack in a perfect linear array.
Human-caused. And it’s recent.
He flicked to another image, this one of borehole geometry plotted against known hydrothermal plumbing. He didn’t understand half of what he was seeing, but the fact Julie had sent it meant he understood the point of it all. Whoever did this had drilled where superheated fluids traveled toward the Norris basin — like tapping veins on purpose.
Reggie glanced. “Those red dots are the drill pads?”
“Yeah.”
“How deep?”
“Logs show eight hundred meters plus,” Ben said. “Maybe more.”
Reggie stared out the windshield. “I know a little about geothermal. That’s not a drill; that’s a letter bomb.”
Ben’s knuckles whitened. He swallowed, tasting stale airplane coffee. “I was a ranger there. Julie was CDC. We both promised we’d never let it happen again. We built a base in Alaska to try to avoid this.”
“Life’s full of jokes,” Reggie said.
They stopped south of town for gas and road sandwiches. While the pump ran, Ben leaned against the SUV and called home again. Julie answered on video this time. Hope occupied her lap, hair static-charged under a fleece hood, a plastic moose clutched in one fist.
“Dada!” Hope squealed. She hammered the screen with her free hand.
Ben’s chest pinched. “Hey, Tadpole.” He kissed the camera. “Daddy’s gotta work a little longer. Be good for Mom.”
Hope offered the toy moose to the phone. Julie angled the screen so he could see the ops annex behind her: three monitors, a map of the Yellowstone caldera glowing in false color, lines of sensor code running like green rain. One entire wall of the annex was decorated to look like the log cabin it had been built onto; the rest looked like a submarine control room welded to a hunting lodge. Their life in a frame.
“You good?” she asked.
“I’m fine,” he lied. “We’re fueling. Quick stop at Centennial, meet your pet geo-nerd, then hell.”
“I’ll keep you posted,” she said. “I set a secure tunnel into the park’s maintenance net in case you need door overrides. Don’t get arrested.”
He laughed, weak. “That was one time.”
“Twice,” she said. “You said there was also an elk-hazing incident?”
He groaned. She winked. “Love you. Bring him back.” She kissed Hope’s head, then the camera, and killed the call before he could change his mind.
He stood a long moment in the thin gas-station wind, staring at mountains that weren’t the ones he called home. The Chugach rose in his mind: blue ridges, alpenglow, their cabin lantern bright in winter dark. He’d get back.
He had to.
Traffic bled out as they angled south toward Centennial. Urban sprawl gave way to winter pasture and distant foothills. Reggie tapped the steering wheel. “You think the backup generator behaved while you were gone?”
“Depends whether the moose leaned on the fence again,” Ben said. “Last time it knocked the dish out and Julie had to patch a data hole using a weather balloon and fishing line.”
Reggie shook his head. “Only outfit I know where HQ is a log cabin with an EMP cage and a toddler gate, especially when we’re funded by a guy who started one of the richest communications companies on the planet.”
“Recruiting pitch writes itself,” Ben said.
They crested a low rise; the runways at Centennial flashed silver in the sun. Maintenance hangars lined the far side. Parked outside one of them was a gray Bell 412, rotor tied, panels open, fuel truck attached. A woman in a flight suit paced with a clipboard.
Ben’s stomach tightened. “We’re really doing this.”
“We always were,” Reggie said.
He turned to Ben, sober now. “Last time Yellowstone tried to kill you, you weren’t a dad.”
“Nope.”
“That change how you play it?”
Ben watched a contrail smear the sky. “It changes how I finish it.”
They rolled through the gate. The pilot strode over, grinning through wind-chapped lips. “Which one of you clowns owes me a favor?”
“Both,” Reggie said.
“Great,” she said. “Load fast. Weather window’s narrow. Your science liaison’s already wheels-up from Bozeman.”
Ben grabbed his duffel. The rotor tie-down snapped free. The Bell’s turbine spooled with a hungry whine.
He glanced once west — toward Wyoming, toward the caldera that made and nearly unmade his life. Then he climbed aboard.
