Fuck.

“AMASE is over three hours from my creva—location. If you really do get here in thirty minutes, we’re not going to make it there in time to avoid the storm. You are not going to make it back in time, and I’m not going to let something terrible happen to you just because I—”

“I’m not coming from AMASE,” he says. “And that’s not where we’re going.”

“But how did you even access my GPS tracker if you’re not at AMASE?”

A pause. “I’m good with computers.”

“You’re— Are you saying you hacked your way into—”

“They mentioned you’re injured. How bad is it?”

I glance at my boots. Ice crystals have begun to crust around the soles. “Just a few scrapes. And a sprain. I think I could maybe walk, but—I don’t know about sixty minutes.” I don’t know about sixty seconds. “And on this terrain—”

“You won’t have to walk at all.”

I frown, even though my brow is almost frozen. “How will I get to wherever we’re going if—”

“Do you have ascenders?”

“Yes. But again, I don’t know if I can climb . . .”

“No problem. I’ll just haul you out.”

“You . . . It’s too dangerous. The terrain around the edge might collapse and you’d fall in, too.” I let out a choppy breath. “Ian, I cannot let you.”

“Don’t worry, I’m not in the habit of falling inside crevasses.”

“Neither am I.”

“You sure about that?”

Okay. Fine. I walked right into this one. “Ian, I cannot let you do this. If it’s . . .” I take a shuddering, frigid breath. “If it’s because you feel responsible for this. If you’re risking your life because you think it’s somehow your fault I ended up here, then you really shouldn’t. You know that I have no one to blame but me, and—”

“I am about to start climbing,” he interrupts distractedly, like I wasn’t in the dead middle of an impassioned speech.

“Climbing? What are you climbing?”

“I’ll put away my phone, but get in touch if anything happens.”

“Ian, I really don’t think you should—”

“Hannah.”

The shock of hearing my name—in Ian’s voice, cocooned by the whistle of the wind, and through the metallic line of my satphone, no less—has me instantly shutting up. Until he continues.

“Just relax and think of Mars, okay? I’ll be there soon.”

It’s not that I’m shocked to see him.

That would be, honestly, pretty idiotic. Too idiotic even for me: a well-known occasional idiot. I might not have seen Ian Floyd in over four years—yup, since the day I had the best sex-and-it-wasn’t-even-really-sex-God-what-a-waste-of-my-life and then barely forced myself to wave good-bye at him while the mahogany of his office door closed in my face. It might have been a while, but I’ve kept up with his whereabouts through the use of highly sophisticated technology and cutting-edge research tools.
