“What is it?” Emma asked.

Jonathan stuffed the water bottle into his rucksack. “The storm’s going to get worse before it gets better. We need to make tracks. You sure you don’t want to go back?”

Emma shook her head. No pride this time. Just resolve.

“Alright then,” he said. “You lead. I’ll be on your tail. Give me a second to adjust my bindings.”

Kneeling, Jonathan watched as a track of snow tumbled over the tips of his skis. In seconds, the skis were covered. The tips began to quiver and he forgot all about the bindings.

Warily, he rose. Above his shoulder, the Furga Nordwand, a wall of rock and ice, shot a thousand feet to a craggy limestone summit. Prevailing winds had piled loose snow against the base of the wall, forming a high, broad embankment that appeared choked and unstable. “Loaded,” in the mountaineer’s parlance.

Jonathan’s throat went dry. He was an experienced mountaineer. He’d climbed in the Alps, the Rockies, and even for a season, the Himalayas. He’d had his share of scrapes. He’d come through when others hadn’t. He knew when to be worried.

“Do you feel it?” he asked. “It’s getting ready to rip.”

“Did you hear something?”

“No. Not yet. But…”

Somewhere out there…somewhere above them…the sound of distant thunder rolled across the peaks. The mountain shuddered. He thought of the snow on the Furga. Days of unremitting cold had frozen it into a mammoth slab weighing thousands of tons. It wasn’t thunder he heard, but the noise of the slab cracking and breaking free from the older, crustier snow beneath it.

Jonathan stared up at the mountain. He’d been caught in an avalanche once before. For eleven minutes he’d lain beneath the surface, entombed in darkness, unable to move a hand, even a finger, too cold to feel that his leg had been yanked out of its socket and twisted backward so his knee was inches from his ear. In the end, he’d survived because a friend had seen the cross on his patrolman’s jacket a moment before he’d been swept under.

Ten seconds passed. The rumbling died. The wind slackened and an eerie quiet reigned. Without a word, he unwound the rope coiled round his midsection and fastened an end around Emma’s waist. Retreat was no longer an option. They needed to get out of the path of the coming avalanche. Using hand signals, he motioned that they would be taking a path directly up the face and that she was to follow closely. “Okay?” he signaled.

“Okay,” came the reply.

Pointing his skis up the hill, Jonathan set out. The face rose steeply, following the flank of the mountain. He kept a demanding pace. Every few steps he glanced over his shoulder to find Emma where she should be, no more than five paces behind. The wind picked up and shifted to the east. Snow attacked in horizontal slats, clawing at the folds of their clothing. He lost all feeling in his toes. His fingers grew numb and wooden. Visibility dwindled from twenty feet to ten, and then he couldn’t see beyond the tip of his nose. Only the burn in his thighs told him that he was moving uphill and away from the ravine.

He crested the ridge an hour later. Exhausted, he anchored his skis and helped pull Emma up the final few feet. Lifting her skis over the edge, she collapsed in his arms. Her gasps came in spasmodic gulps. He held her close until she found her breath and was able to stand on her own.

Here, in the saddle of two peaks, the wind pummeled them with the fury of a jet engine. The sky, however, had partially cleared, and Jonathan was granted a fleeting view down the valley that led to the village of Frauenkirch, and beyond it, Davos.

He skied to the far side of the ridge and looked over the cornice. Twenty feet below, a chute of snow plummeted like an elevator shaft between outcroppings of rock. “This is Roman’s. If we can get down here, we’ll be okay.”

Roman’s was part of the local lore, named for a guide killed by an avalanche while skiing down it. Emma’s eyes opened wide. She looked at Jonathan and shook her head. “Too steep.”

“We’ve done harder.”

“No, Jonathan…look at the drop. Isn’t there another way?”

“Not today.”

“But…”

“Em, we get off this ridge or we freeze to death.”

She moved closer to the lip, craning her neck to get a good look at what lay below. She pushed back, her chin resting on her chest. “What the hell?” she said, not half meaning it. “We’re here. Let’s do it.”

“Just a little drop, a quick turn, and it’s all cake. Like I said, we’ve done harder.”

Emma nodded, more certainly now. And for a moment she gave the illusion that nothing was out of order, that they weren’t flirting with frostbite, and that she’d been looking forward to testing herself against this near-suicidal chute all along.

“Okay then.” Jonathan removed his skis and peeled off the skins. Gripping one ski like an ax, he cut a three-foot-square slab of snow and dropped it over the edge. The slab struck the incline and tumbled down the mountain. Here and there, trails of snow dribbled lazily, but the slope held firm.

“Follow me down,” he said. “I’ll mark the trail.”

Emma came alongside him, the tips of her skis dangling over the cornice.

“Get back,” he said, hurrying to put on his skis. She had the look. He didn’t even need to see her to know it. He could sense it. “Let me go first.”

“Can’t let you do all the heavy lifting.”

“Don’t even think about it!”

“Last one down, remember?”

“Hey…no!”

Emma pushed off, hung for a moment, then dropped to the slope, skis striking the ice with a sizzle. She landed awkwardly and traversed the chute at lightning speed, her downhill ski slightly askew, pressed hard against the snow. Her hands were too high; her body too far over her skis. Her entire figure looked ungoverned, out of control. Jonathan’s eyes shot to the rocks bordering the chute. Turn! a voice shouted inside him.

Ten feet separated her from the rocks. Five. The next instant, she executed a perfect jump turn and reversed her direction.

Jonathan relaxed.

Emma raced across the chute and made another flawless turn. Her hands dropped to her side. Her knees flexed to absorb any hidden bumps. All signs of fatigue had vanished.

He raised a fist in triumph. She had done it. In thirty minutes, they would be seated in a booth at the Staffelalp restaurant in Frauenkirch, two steaming cafés Lutz in front of them, laughing about the day and pretending that they’d never been in any danger. Not really. Later, they would go to the hotel, fall into bed, and…

Emma fell making the third turn.

Either she caught an edge or she turned a half second too late and nicked her skis against the rocks. Jonathan’s stomach clenched. Horrified, he watched as she carved a scar down the center of the chute. Her hands clawed at the snow, but the incline was too steep. Too icy. Faster she went. And faster still. Striking a bump, her body was flung into the air like a rag doll. She landed with one leg twisted beneath her. There was an explosion of snow. Her skis shot into the air as if launched from a cannon. She began to starfish, arms and legs akimbo, cartwheeling head over heel.

“Emma!” he cried out, launching himself down the chute. He skied with abandon, arms flung wide for balance, his body taut, attacking the hill. A veil of mist crossed the slope, and for a moment, he was lost in white, visibility nil, with no idea which way was up or down. He straightened his skis and shot through the cloud.

Emma lay far down the slope. She had come to rest on her stomach, head below her feet, face dug into the snow. He stopped ten feet away from her. Stepping clear of his skis, he took high, bowlegged strides through the powder, his eyes hunting for a flicker of movement. “Emma,” he said firmly. “Can you hear me?”

Slinging off his daypack, he fell to his knees and cleared the snow from her mouth and nose. Placing a hand on her back, he felt her chest rise and fall. Her pulse was strong and steady. Inside his pack was a nylon mesh bag holding a spare cap, mittens, goggles, and a Capilene shirt. He folded the shirt and placed it under her cheek.
