James Rollins - Amazonia

"It's right on top of you!"

Nate didn't bother to turn. He ran toward the tangle of mangrove roots, shoved Kelly between them, then dove in after her. There was a cramped natural cavity behind the main buttress roots.

Kelly groggily awoke, coughing out gouts of water and staring around in panic. Nate fell atop her in the small space.

"What . . . ?"

Then, over his shoulder, she must have spotted their pursuer. Her eyes grew large. "Oh, shit!"

Nate rolled around and saw the monster hurling itself up out of the lake, scrabbling up the short bank. It struck like a locomotive hitting a car on the tracks. The whole tree shook. Nate was sure it would crash atop them. But the tree held. The caiman stared at Nate between the roots, mouth gaping open, teeth glinting with menace. It paused, glaring at him, then backpedaled and slid into the waters.

Kelly turned to him. "You saved me:"

He glanced to her, their noses almost touching in the cramped root prison. "Or almost got you killed. It's all perspective, really." Nate pushed to his knees. He grabbed one of the roots to haul himself to his feet. "And we're not out of the woods yet:"

Nate studied the waters, watching for any telltale ripple. It seemed quiet. But he knew the caiman was still out there, watching. Taking a deep breath, he squeezed back out between the roots.

"Where are you going?"

"There are still others in the water . . . including your brother." Nate shoved the napalm bomb under his shirt and began to climb the mangrove, a plan slowly forming. Once high enough, he picked a good branch, clambered atop it, and slowly crawled down its length to where it hung over the water. As the branch thinned, it began to bend under his weight. He moved more cautiously.

At last, he could risk going no farther. He glanced down and around his perch. This would have to do.

He called to the other raft while pulling out the bomb. "Does anyone know how to arm one of these explosives?"

Sergeant Kostos answered, "Type in the time delay manually! Then hit the red button!"

Waxman yelled from where he floated in the water. Nate had to respect how calm the captain's voice was as he added a warning. "It's got an explosive radius of a couple hundred meters. Blow it wrong and you'll kill us all!"

Nate nodded, staring at the bomb. A simple sealed keyboard glowed atop it, not unlike a calculator. Nate prayed it hadn't been damaged by the dunking or abuse. He set the timer for fifteen seconds. That should be long enough.

Next, Nate cradled the bomb to his chest and snapped free his work knife. Clenching his teeth, he dug the blade into the meat of his thumb and sliced a deep gash. He needed the wound to bleed freely.

Once done, he used a secondary branch as support and climbed to his feet on the swaying perch. He pulled the bomb out with his bloodied hand and made sure he had a good grip. Stretching out over the water, Nate extended his arm, bomb in hand. Blood dripped over the weapon's surface and down to the waters below, plopping in thick drops and sending out ripples.

He held steady, his thumb on the trigger button. "C'mon, damn you." In Australia, he had once visited a live animal park and had seen a thirty foot saltwater crocodile trained to leap after a freshly decapitated chicken on a pole.

Nate's plan wasn't much different. Only he was the chicken.

He slightly shook his arm, scattering more drops. "Where are you?" he hissed. His arm was getting tired.

Down below, he watched a small pool of his own blood forming on the surface of the water. A caiman could smell blood in the water from miles away. "C'mon!"

Squinting, he risked a peek toward the others still afloat in the debris field. With no way of knowing where the caiman was, neither of the other two rafts dared paddle to their mates' rescue.

Distracted, Nate almost missed the flash of something large heaving through the shallows toward him.

"Nate!" Kelly called.

He saw it.

The caiman lunged out of the water, blasting straight out of the lake and springing toward him, jaws wide open, roaring.

Nate hit the bomb's trigger, then dropped the blood-slick device down the open mouth. He realized at the same time that he had vastly underestimated how high a giant swamp caiman could leap.

Nate crouched on his branch, then leaped straight up, propelled by both his legs and the spring in the branch. Crashing through leaves, Nate grabbed a limb overhead. He yanked his feet out of the way just as the monster's jaws snapped shut under the seat of his pants. He felt its huffed breath on his back. Denied its prey, it fell back to the water, shooting spray almost as high as its leap.

Staring down, Nate saw the branch he had been perched on. It was gone, a stump, cleaved clean through by those mighty jaws. If he had still been standing there . . .

Nate saw the caiman again glide from the shallows into the deeper waters, but now it remained floating on the surface, revealing its length. A male, 120 feet if it was an inch.

Hanging from the branch, Nate caught a frustrated glower directed up at him. It slowly turned toward where the others were floating, giving up on him for the moment and going after easier prey.

Before it could complete its turn, Nate saw the beast suddenly shudder. He had forgotten to count the seconds.

Suddenly the belly of the beast swelled immensely. It opened its maw to scream but all that came out were jets of flame. The caiman had become a veritable flaming dragon. It rolled on its side and sank into the murkier depths, then a huge whoosh exploded upward in a column of water, flames, and caiman.

Nate clung to his perch with his arms and legs. Down below in the roots, Kelly yelled in shock.

The blast ended as quickly as it blew. In the aftermath, bits and pieces of flaming flesh showered harmlessly around the swamp. Insulated by the armored bulk of the great giant, the worst of the bomb's effect had been contained.

A shout of triumph arose from the others.

Nate climbed down the tree and retrieved Kelly. "Are you okay?" he asked her.

She nodded, fingering a gash at her hairline. "Head hurts a little, but I'll be fine:" She coughed hoarsely. "I must've swallowed a gallon of swamp water."

He helped her down to the water's edge. While Kostos's raft went to collect the swimmers and packs, Nate's own raft, manned by his friends and Ranger Camera, glided over to the pair to keep them from having to swim.

Camera helped pull Kelly aboard. Manny grabbed Nate's wrist and hauled him up onto the bamboo planks. "That was some pretty fast thinking, doc," Manny said with a grin.

"Necessity is the mother of invention," Nate said, matching his expression with a tired smile. "But I'll be damned glad to be on dry land again.

"Could there be more of them out there?" Kelly asked as the group paddled toward the other raft.

"I doubt it," Manny said with a strange trace of regret. "Even with an ecosystem this large, I can't imagine there's enough food to support more than two of these gigantic predators. Still, I'd keep a watch out for any offspring. Even baby giants could be trouble:"

Camera kept watch with her rifle as the others paddled. "Do you think that the Ban-ali sent these after us, like the locusts and piranhas?"

Kouwe answered, "No, but I would not put it past them to have nurtured this pair as some de facto gatekeepers to their lands, permanently stationed guards against any who dared to enter their territory"

Gatekeepers? Nate stared at the far shore. The broken highlands were now clear in the afternoon brightness. Waterfalls were splashes of silver flowing down cliffs the color of spilled blood. The jungled summits and valleys were verdant.

If the professor was right about the caiman being gatekeepers, then ahead of them stretched the lands of the Ban-ali, the heart of their deadly territory.
