Faces flushed. Lips cracked. Those still carrying Chap-stick even used it on their splitting cuticles. By the thirtieth hour, they knew what it was like to be roasted alive. Head draped with a red-and-white checkered cotton scarf, Ike warned them to keep covered. The NASA survival suits were supposed to wick their sweat to a second layer to circulate and cool. But the humidity inside their suits became unbearable. Soon everyone had stripped to underwear, even Ike in his kayak. Appendix scars, moles, birthmarks all went on display; later the revelations would fuel new nicknames.
Ali had never known thirst like this.
'How much longer?' a voice croaked from the line. Ike grinned. 'Drink,' he said.
They moved on, mouths open. The batteries of their boat motors had run down. They paddled listlessly, spooning at the river.
At one point the tunnel wall became so hot, it glowed dull red. They could see raw
magma through a gash opened in the wall. It arched and seethed like gold and blood, roiling in the planetary womb. Ali dared one glance and darted her face away and stroked on. Its hush was like a great geological lullaby.
The river looped around and through the volcano's searing root system. There were, as always, forks and false paths. Somehow, Ike knew which way to go.
The tunnel began to close on them. Ali was near the end of the line. Suddenly screams issued from the very back. She thought they were under attack.
Ike appeared, his kayak scooting upriver like a water bug. He passed Ali's raft, then stopped. The walls had plasticized and bulged in on the tunnel, confining the very last raft on its upriver side.
'Who are they?' Ike asked Ali and her boatload.
'Walker's guys,' someone answered. 'There were two of them.'
The shouting on the far side of the opening was anonymous. The hemorrhaged stone made a noise like a ship's ribs cracking. The outer sheath of stone splintered, throwing shrapnel.
Walker and his boat of men came paddling from lower down. The colonel assessed the situation. 'Leave them,' he said.
'But those are your men,' Ike said.
'There's nothing to be done. It's already too narrow to get their raft through. They know to retreat if they get cut off.' The soldiers in Walker's boats were lockjawed with fear, veins snaky from wrist to shoulder.
'Well, that won't do,' Ike said, and shot upriver.
'Get back here!' Walker shouted after him.
Ike darted his kayak through the narrowing channel. The walls were deforming by the minute. Part of his checkered scarf touched the walls and caught fire. The hair on his head smoked. He popped through the maw at full speed.
The sides bloated in behind him. The bottom ten feet of the opening fused shut with a kiss. A gap remained open near the ceiling, but it was easily nine hundred degrees Fahrenheit through there. No one could conceivably climb through.
'Ike?' called Ali.
It was as if he had just changed into solid rock.
The new wall quickly choked back the river. Even as Ali's boat of people sat there, the river's bottom grew more exposed, inch by inch. The corridor was filling with steam. It was going to be a race to keep ahead of the deprivation.
'We can't stay here,' someone said.
'Wait,' Ali commanded. She added, 'Please.'
They waited and the riverbed drained lower. In another few minutes their raft would be sitting upon bare stone.
Ali's cracked lips parted. God the Father, she prayed. Let this one go free.
It was not like her. True devotion was not quid pro quo. You never cut deals with God. Once, as a child, she had pleaded for her parents' return. Ever since, Ali had decided to let be what was. Thy will be done.
'Let him live,' she murmured.
The walls did not open. This was not a fairy tale. The stone stayed welded.
'Let's go,' said Ali.
Then they heard a different sound. Dammed on the far side, the river had built height. Abruptly, a jet of water shot through the molten aperture at the top.
'Look!'
Like Jonah being vomited from the whale, one, then two men came blasting from the hole. Sheathed in water, they were protected from the scalding rock and thrown clear into the lower river.
The two soldiers staggered downstream through the thigh-deep water, weaponless, burned, naked. But alive. The raft of scientists returned and pulled the two bleating,
shocked men onto their floor. 'Where's Ike?' Ali yelled to them, but their throats were too swollen to speak.
