The stone lid slid off the sarcophagus, skittered across the tilted floor, and toppled into the gaping hole under Gray's feet. His flashlight had already rolled into the pit. Its shine revealed a bottom covered in vicious bronze spikes, all pointed up.

The stone lid crashed and shattered against them.

Behind Gray, the floor continued to tip, going vertical, trying to dump everyone below.

Wallace and Rachel had managed to get behind the sarcophagus and brace themselves. The coffin remained in place, anchored to the floor. Seichan couldn't reach the refuge in time. She went sliding toward the pit.

Rachel lunged out with an arm and caught the back of her jacket as she slid past. She pulled Seichan close enough so the woman could grab the edge of the sarcophagus.

Rachel continued to hold her. At the precarious moment, each woman depended on the other for her life.

As the floor tilted to full vertical, Seichan hung like Gray.

But Gray had no one holding him.

His fingers slipped, and he plummeted toward the spikes.

Chapter 22

October 13, 1:13 P.M.

Svalbard, Norway

The warhead detonated on schedule.

Even hidden behind two steel doors and walls of bedrock, Painter felt the blast as if a giant had his hands over his ears, trying to crush his skull. And yet he still heard the other two seed banks' air locks blow. From the concussive sound of it, the same giant had stamped his foot and crushed the other chambers flat.

Crouched beside their air lock, Painter heard the outer door give way and slam into the inner one with a resounding clang. But the last door held. The overpressure in the air lock had been enough to hold off the sudden blast wave.

Painter touched the steel door with relief. Its surface was warm, heated by the thermobaric's secondary flash fire.

The lights had also been snuffed out by the blast. But the group had prepared for that. Flashlights had been passed out, and they flickered on across the chamber like candles in the dark.

"We made it," Senator Gorman said at his side.

His voice sounded tinny to Painter's strained ears. The others began picking themselves up off the floor. Cries of relief, even a few nervous laughs, spread through the assembled guests and workers.

Painter hated to be the bearer of the bad news, but they had no time for false hope.

He stood up and lifted his arm. "Quiet!" he called out and gained everyone's attention. "We're not out of here yet! We still don't know if the explosion was enough to break through the wall of ice trapping us down here. If we're still stuck, rescue could take days."

Painter motioned to the vault's maintenance engineer for confirmation. He lived up here. He knew the terrain and the archipelago's resources.

"It could take well over a week," he said. "And that's if the road is still open."

That was doubtful, considering the missile barrage Painter had heard. But he kept that to himself. The news was bad enough already. And he had more to deliver.

Painter pointed to the door. "The firestorm will have burned away most of the available oxygen and turned the air toxic out there. Even if the exit is open, these lower levels will still be choked with bad air. We're in the only safe pocket down here. But it will only last for a couple of days, maybe three."

The engineer looked like he was going to shorten that projection, but Painter stemmed that with a hand on his arm. Painter also avoided telling the group the real reason for his haste.

Whoever attacked could come back.

The crowd had gone completely quiet as the sobering news sank in.

Karlsen finally spoke from the edge of the crowd. These were mostly his guests. "So what do we do?"

"Someone has to go out there. To check the door. If it's open, they're going to have to make a long run through a toxic soup. Someone needs to get out and bring back help. The rest will stay here where it's safe for the moment."

"Who's going to go out there?" Senator Gorman asked.

Painter lifted his hand. "I am."

Karlsen stepped forward. "Not alone you're not. I'll go with you. You may need an extra pair of hands."

He was right. Painter didn't know what he might encounter out there. There could be a partial cave-in, a tangle of damaged equipment. It might take a couple of people to move an obstacle. But he eyed Karlsen with skepticism. He was not a young man.

Karlsen read the doubt in his face. "I ran a half marathon two months ago. I jog daily. I won't hold you back."
