Queen Maud Land, Antarctica

“Where’s the damned sun?” Kowalski groaned.

Gray understood the big man’s frustration. He stood in the pilothouse of the massive treaded vehicle and studied the landscape beyond its tall windows. Though it was midmorning, it was pitch-black outside. With the moon already down, bright stars twinkled coldly across a cloudless sky. Occasional ethereal waves of brilliance rolled across the starscape, in hues of emerald and crimson, amid splashes of electric blue.

This dramatic storm of the aurora australis—the southern polar lights—had chased them across the frozen expanse of Queen Maud Land during their overnight trek. The fierceness of the display reflected the severity of the solar flare that compromised satellite communication across Antarctica. Each dazzling dance of the aurora reminded Gray how isolated they were out here.

He studied the terrain for some clue to where they were going. After abandoning Karen and the other researchers at the lone remaining Halley module, Gray and his team had headed east in the large vehicle, trundling across a flat sea of snow and ice. According to the dynamic map display above the pilot’s station, their path paralleled the distant coastline. But out the window, there was no sign of sea or ocean, just a frozen world of white and blue. The only feature that broke up the monotonous landscape rose to the south of their position. A line of black craggy peaks poked out of the ice, marking the tops of buried mountains. Razor-sharp, the crags looked like a row of fangs and were in fact named Fenriskjeften—or the Jaws of Fenris, named after the mythic Nordic wolf.

Conversation drew his attention back to the control deck behind him—and to their host, Stella Harrington, daughter of the reclusive professor they were headed to meet.

“We actually designed our CAAT after the prototype built by DARPA,” Stella explained to her avid pupil.

Jason stood next to her at the helm station, looking at a set of schematics for their strange vehicle. He plainly could not get enough information about their unique mode of transport.

Or maybe it was his teacher.

In her early twenties, Stella was the same age as Jason, with a pixie blond cut, stunning green eyes, and curves that showed even through her heavy wool sweater and thick polar pants. She was also whip-smart, holding a dual master’s in botany and evolutionary biology, a challenging match for Sigma’s resident computer genius.

“I remember seeing a video of that DARPA prototype,” Jason said. “It was one-fifth this size. Can you still travel over water in this larger craft?”

“Why do you think it’s called a Captive Air Amphibious Transport?” Stella teasingly rolled her eyes. “Each individual tread of the belts is made of a buoyant foam, allowing us to travel over both land or sea. And out here, that’s important.”

Jason frowned, glancing out to the frozen expanse. “Why do you need to be amphibious out here?”

“Because we use the CAAT mostly—” She suddenly stopped, perhaps knowing she was speaking too freely.

It had been that way since they boarded. Any conversation was laced with gaps and silences. She still hadn’t told them what sort of trouble her father was in, only that he needed their help.

She looked away, her voice lowering guiltily. “You’ll see.”

Jason didn’t press the matter.

“But the CAAT is still useful over the ice,” Stella continued more confidently. “We can get her up to eighty miles an hour on flat terrain, and her length allows us to forge narrow crevasses.”

Jason studied the schematics. “The vehicle reminds me somewhat of Admiral Byrd’s snow cruiser, the big polar truck built just after World War II. Are you familiar with it?”

Gray remembered seeing a picture of that fifty-foot-long polar truck, capable of carrying a small plane on its back. The photo had been found in Professor Harrington’s files that had been recovered from DARPA’s servers.

“I . . . I am,” Stella said, again speaking tentatively, as if she were walking on thin ice. “My father believed the CAAT could serve a similar role.”

Jason nodded. “Makes sense.”

The kid cast Gray a surreptitious glance. Gray suddenly realized Jason had been quietly testing Stella, using information from her father’s files to see how open she would be with them.

Maybe he wasn’t so moonstruck after all.

“How many people can this CAAT hold?” he asked.

“We’re specked to carry a twelve-person team, including the bridge crew. But in a pinch, we could squeeze in another six or seven.”

It was why they had to abandon Karen and the others. Gray had seen the cramped quarters down below. It seemed the vehicle’s engine and mechanics took up most of the available space. The crew’s quarter held a tiny mess hall and bunkroom, and Stella had come with a full complement of British soldiers, all armed, expecting they might run into trouble. There was no way the CAAT could carry Karen and all twelve of her fellow researchers.

But that was never an option.

Stella made it clear that Professor Harrington would allow only Gray and his two men to be ferried across Queen Maud Land to his secret base. It seemed the man’s paranoia had only grown worse upon hearing about the attack. Stella had been en route by air when she picked up their radio chatter after Gray escaped from the destroyed base. She promptly turned around and sought out the CAAT, which was already out on the ice for a different mission. She made an emergency landing and rerouted the treaded tank for her rescue mission.

In a small concession, she had left two British soldiers with Karen and the others—along with rocket launchers and heavy weapons—in case the enemy managed to hunt down that roving module. It was the best that could be made of the situation.

Gray joined Jason at the helm. “How much longer until we reach our destination?”

Stella glanced over to the map on the dynamic positioning system above the pilot’s head. She studied it for too long, plainly trying to weigh how much to say.

Jason interceded, applying a boyish lightness to his words. “It’s not like we can tell anyone.”

She kept staring at the map, but Gray noticed the ghost of a smile edge her lips. “I suppose that’s true.” She pointed to the DPS screen. “See that small peninsula shaped like a half-moon? About twenty miles away. That’s Hellscape.”

“Hellscape?” Jason asked, bunching his brows at the ominous-sounding name.
