“Just out on a promenade.” He sounds a little out of breath, which means that the climb must have been a tough one. Ian is lots of things, but out of shape is not one of them. “Taking in the scenery. What about you? What brings you here?”

“I’m serious. Why are you in Norway?”

“You know”—the sound briefly cuts, then bounces back with a generous helping of white noise—“not everyone vacations in South Padre. Some of us enjoy cooler destinations.” The huffing and puffing through the tenuous satellite line is almost . . . intimate. We’re exposed to the same elements, on the same heavily glaciated terrain, while the rest of the world has taken shelter. We’re out here, alone.

And it doesn’t make any sense.

“When did you fly into Svalbard?” It couldn’t have been any time in the last three days, because there were no incoming fights. Svalbard is well connected to Oslo and Tromsø in the peak season, but that won’t start until mid-March.

So . . . Ian must have been here for a handful of days. But why? He is chief of engineering on several rover projects, and the Serendipity team is approaching crunch time. It makes no sense for one of their key personnel to be in another country right now. Plus, the engineering component of this AMASE is minimal. Only Dr. Merel and me, really. All other members are geologists and astrobiologists, and—

Why the hell is Ian here? Why the hell would NASA send a senior engineer on a rescue mission that wasn’t even supposed to happen?

“Are you still doing okay?” he asks again. When I don’t reply, he continues: “I’m close. A few minutes away.”

I brush snowflakes from my eyelashes. “When did AMASE change its mind on sending relief efforts?”

A brief hesitation. “Actually, it might be more than a few minutes. The storm’s intensifying and I can’t see very well—”

“Ian, why did they send you?”

A deep breath. Or a sigh. Or a puff, louder than the others. “You ask a lot of questions,” he says. Not for the first time.

“Yeah. But they’re pretty good questions, so I’m going to keep on asking more. For instance, how the—”

“As long as I can ask some, too.”

I nearly groan. “What do you want to know? Best concert? Favorite concert? An overview of the amenities of the crevasse? It offers very little in terms of nightlife—”

“I need to know, Hannah, if you are doing okay.”

I close my eyes. The bite of the cold is like a million needles wedged under my skin. “Yes. I . . . I’m fine.”

Suddenly, the call drops. The static, the noise, they all disappear, and I can’t hear Ian anymore. I glance at my satphone and find it still on. Shit. The problem is on his end. The snow’s getting thicker, it’ll be pitch-black in minutes, and on top of that I’m almost sure that Ian has been attacked by a polar bear. If something happens to him, I’ll never be able to forgive myse—
