A hazmat suit landed loudly at his feet.

  * * *

  Fully suited up, the team made their way into the chasm, steadying themselves on guide ropes that had been set up for the rescue operations. Their flashlights did little to dispel the darkness as they entered a cavern descending steeply into the earth. The sound of his own breathing echoed hollowly inside Serizawa’s protective hood, which felt heavy and unwieldy. The weight of the suit, and his limited visibility, did not make the downward trek any easier.

  Keeping one hand on the guide rope, he held the radiation sensor out before him. The clacking was nonstop now, the needle pegging the dial. Serizawa couldn’t help wondering about the quality and integrity of his hazmat gear. He suspected that Graham and the others were, too. None of them wanted to end up like those wretched souls in the triage center.

  While Serizawa monitored the radiation levels, Graham documented the expedition with her digital camera. Periodic flashes lit up the cavern’s murky interior, exposing fractured stone walls and twisted metal debris. She gasped as a flash revealed a lifeless human hand extending from the rubble. Flashlight beams swung toward the hand, which belonged to a bloated corpse sprawled upon the rocks. A contorted face was frozen in an agonized rictus. Cloudy eyes gazed sightlessly into oblivion.

  “They sent another fifty men down here to search for survivors,” Boyd explained, his voice muffled by his protective breathing apparatus. “Half the rescuers never made it back up, they were too weak.”

  Serizawa did the calculations. That was over sixty-five fatalities so far, not including the doomed and dying men they had just left behind in the triage center. The death count was mounting by the moment and they hadn’t even confirmed the cause yet. He feared, however, that this was indeed far more than just a tragic mining accident.

  Graham’s camera flashed again and again, finding additional bodies scattered in heaps through the cavern. Still more valiant rescue workers, Serizawa realized, who had perished before making it back to the surface. He admired their courage even as he mourned their sacrifice.

  Squinting in the shadows, he looked away from the plentiful dead and studied his surroundings. Each flash from Graham’s camera offered a glimpse of roughly textured cavern walls and oddly curved calcite formations all around them. It was like exploring the interior of some alien moon or world fresh from the dawn of its creation. The rich, green splendor of the Philippine rain forest seemed very far away.

  A work crew from the mine, drafted into service by Boyd, set up globe lights around the spacious interior of the cavern. Serizawa and Graham both gasped out loud as the first of the lights flared to life, giving them a better look at the scene in whole. Thick bands of a porous, calcite-like material ribbed the grotto.

  “The rocks, right?” Boyd said, as though anticipating the scientists’ reaction. “I’ve been digging holes for thirty years, but I’ve never seen anything like it.”

  Serizawa’s eyes widened as he grasped what he was seeing.

  “No,” he said, his voice hushed in awe. “Not geological. Biological.” He raised his flashlight, concentrating its beam on the huge shield-shaped calcite formation that made up the ceiling of the grotto. At least twenty meters in length, its contours were clearly recognizable if you knew what you were looking for. “The ceiling… it’s bone. It’s the sternum. We’re inside a ribcage.”

  Before Boyd could process that, the rest of the globe lights popped, flooding the vast cavern with cold white light. Serizawa turned about, taking in the entire scene. Now that he knew what to look for, the impossible truth was right before his eyes. Gigantic rib bones, curving upwards like the buttresses of a medieval cathedral, formed the walls of the “cavern.” A bony spine, composed of huge, boulder-sized vertebrae, ran across the floor beneath their feet, stretching the length of several football fields. Serizawa realized that he was literally standing on the long-buried backbone of some incredibly gargantuan lifeform.

  Graham stepped away from Boyd, before the speechless foreman could start pelting them with questions. Like Serizawa, she rotated slowly to absorb the full magnitude of what they had discovered. Her eyes were wide behind the visor of her gas mask. She drew closer to Serizawa.

  “Is it Him?” she asked quietly. “Is it possible?”

  Serizawa shook his head. “This is far older.”

  A hush fell over the cavern as everyone coped with Serizawa’s stunning revelation. Boyd shook his head in disbelief, while some of the work crew looked like they were on the verge of bolting. Serizawa recalled the myth of Jonah and the whale, as well another legend native to the small Japanese fishing village where he’d grown up…

  “Guys!” a voice called out from deeper within the cavern. It belonged to Kenji, a young graduate student who had recently joined Serizawa’s team. “You gotta see this!”

  The urgency in Kenji’s voice could not be missed. Serizawa and the others hurried toward him, while trying not to stumble over the rubble and vertebrae. They found Kenji standing under a beam of natural daylight shining down from above. The sunshine lit up more of the cavern’s interior, allowing an even better view of the colossal skeletal remains, but that was not what immediately caught Serizawa’s attention. His eyes were drawn to yet another astounding discovery.

  Two gigantic sac-like encrustations hung like barnacles from the colossal breast bone that formed the ceiling of the cavern. Each the size of a large boulder, the sacs had a rough, gnarled texture that might have formed from some kind of hardened resin or other secretion. Even more than the skeletal structure of the cavern, the sacs appeared unmistakably organic. Serizawa, whose background was in biology, thought that they resembled the egg sacs of some unknown organism, albeit of unprecedented proportions.

  He aimed the radiation sensor at the closest sac, which elicited a flurry of clacking from the detector, but when he turned the sensor toward the further sac, the clacking died off noticeably. The detector registered only the pre-existing background radiation of the cavern.

  Interesting, he thought. Theories and possible explanations began to form within his brain. Although he had devoted much of his career to the covert study of unknown megafauna, he had never encountered specimens like these before. Was it possible that…?

  “That one,” Kenji pointed out. “The one that’s broken. It’s almost as though something came out of it…”

  Indeed, one of the enormous sacs appeared to have shattered from the inside. Giant chunks of its husk were strewn about the floor of the cavern, dozens of feet below the ruptured specimen. Serizawa made a mental note to have every fragment collected for analysis. The nature of material might provide valuable clues into what sort of organism had produced it.

  “Wait,” Kenji said. Fear entered his voice as the full implications of his observation sank in. “Did something actually come out of there?”

  Serizawa refrained from replying. There were too many unsanctioned ears present and he had no desire to start a panic. Instead he headed toward the sunlight, joining Kenji in a wide circle of warm golden light. Tilting his head back, he peered upward.

  High above his head, a ragged hole in the ceiling opened up onto the outside world—almost as though something had burst outward from the depth of the cavern, leaving the ruptured sac behind. He exchanged more apprehensive looks with Graham. This was far more than they had anticipated.

  Hours later, as their chopper ferried them away from the site, Serizawa got a birds-eye view of the giant sinkhole that had broken through the floor of the jungle. Nearly sixty meters in diameter, the hole was even bigger than it had looked from below. But that wasn’t all that alarmed him. Beyond the gaping pit, a massive drag mark stretched across the hilly rain forest, leaving a trail of crushed and uprooted trees and foliage. Acres across, the trail gouged a disturbingly wide path toward the north end of the island—and the open Pacific beyond.

  Serizawa could only wonder what had emerged from the pit.

  And where it was he
ading now.

  THREE

  1999

  The alarm clock jolted Ford Brody from sleep. One minute he’d been dreaming about riding a dragon through outer space, the next he found himself back in his bedroom in suburban Japan. Dawn streamed through the window curtains. Only nine years old, the boy smacked the snooze button on the clock and buried his face back into his pillow. Maybe he could get in a few more moments of sleep before his mom dragged him out of bed.

  Then he remembered what day it was.

  His eyes lit up and a mischievous smile spread across his face. He slid out of bed and tiptoed across the floor, which was littered with toy soldiers, tanks, and dinosaurs. Just last night, right before going to bed, he’d staged an epic battle between the miniature army-men and a ferocious Tyrannosaurus Rex. As usual, the dinosaur had won…

  The glow of a heat lamp caught Ford’s eyes. Despite his big plans for the morning, he detoured over to his terrarium to check on the butterfly cocoon dangling from a branch inside the glass case. To his slight disappointment, the cocoon had not hatched overnight. He impatiently tapped on the glass, trying to provoke a response, but the pupa inside the cocoon refused to cooperate.

  Oh well, Ford thought, shrugging. Maybe tomorrow.

  In the meantime, he had other business to attend to. There was a reason he had set the alarm to wake him up an hour early. He had a lot to accomplish before his dad woke up.

  But as he snuck out into the hall, still in his pajamas, he was dismayed to hear Joe Brody’s voice coming from his office at the end of the corridor. Creeping closer, Ford saw his dad pacing back and forth across the work-filled office, talking urgently into the phone:

  “—I’m asking—Takashi—Takashi—I’m asking for the meeting because I don’t know what’s going on. If I could explain it, I’d write a memo.”

  Shaking his head, Joe ran a hand through his unruly reddish-brown hair. Early morning stubble dotted his anxious face. Glasses perched on his nose. He threw an exasperated look at Ford’s mom, Sandra, who hovered in the doorway to the office, listening intently to her husband’s side of the conversation. Her short black hair needed combing, and she had a robe on over her nightgown. Ford didn’t understand what the problem was, but he figured it had something to with his parents’ work at the nuclear power plant. The family had relocated from San Francisco a few years ago so that they could both get good jobs at the plant.

  “Because Hayato said it had to come from you,” Joe said impatiently.

  His mom heard Ford shuffling behind her. She turned away from the office to spot him in the hallway. He crept up beside her, distraught over this unexpected turn of events.

  “He’s awake?” he whispered.

  Her face transformed in an instant, going from concerned professional to sympathetic mom right away. She knelt down to look Ford in the eye. She mussed his light brown hair.

  “I know!” she whispered back. “He got up early.”

  Ford’s heart sank. Of all mornings for there to be a problem at the plant. “What’re we gonna do?”

  “Get dressed,” she instructed him, flashing a conspiratorial smile. “I’ll figure it out.”

  * * *

  Sandra watched her son scamper back to his room before turning her attention back to more grown-up affairs. Joe barely looked up as she re-entered the office, which was neatly organized despite all the graphs and reports piled about. Printouts of an unidentified waveform pattern were spread out atop his desk, alongside a stack of zip disks.

  “… my data starts two weeks ago,” he explained into the phone. “I’ve got fourteen days of anomalous signal; pulsing between seventy five and a hundred kilohertz, then suddenly today it’s like the same thing but an echo. I’ve ruled out the turbines, internal leakage, we’ve checked every local RF, TV and microwave transponder. I’m still sitting here with two hundred hours of graph I can’t explain.” He paused, listening to someone at the other end of the line. “No—No—the fact that it’s stopped is not reassuring. That’s not good, that’s not the message here.”

  He belatedly noticed Sandra waiting by the doorway. He placed a hand over the phone’s receiver. “What’s going on?”

  “Your birthday?” she reminded him. “Someone is preparing your ‘surprise’ party…”

  Understanding dawned on his face, but she could tell this was the last thing on his mind right now. Flustered, he nodded at her, acknowledging that he’d gotten the message, but making no effort to get off the phone. He held up his hand, signaling that he needed a few more minutes.

  Sandra frowned, giving him a gently chiding look, but let him get back to his call. Lord knew she understood how troubling this new data was. She shared her husband’s worries.

  “… But that’s—hang on—that’s exactly my point,” he insisted. “The moment these pulses stopped is when we started having the tremors.” He irritably shuffled a stack of zip disks from his desk. “With all due respect, Takashi, and honor. Respect and honor. With all of that, okay? I’m an engineer and I don’t like coincidences and I don’t like unexplained frequency patterning near a plant that’s my responsibility. I need a meeting. Make it happen.”

  He was still arguing with Takashi as she left to check on Ford, who had already gotten into his school uniform. They waited until Joe disappeared into the master bedroom to change for work, then hurriedly hung a string of cardboard letters over the archway of the office door. The handmade sign read: “HAPPY BIRTHDAY, DAD!”

  Grinning, she and Ford admired their work. They high-fived each other. Ford beamed in anticipation of his dad’s reaction.

  But when Joe emerged from the bedroom, freshly shaven and wearing a suit and tie, he walked right by the banner without even noticing. His phone was glued to his ear and he spoke rapidly in Japanese on his way out the front door. “Come on,” he called out to Sandra and Ford, switching back to English. “We gotta go!”

  Crushed, Ford looked up at Sandra. “It rocks,” she assured him. “He’ll see it when he gets home, I promise.”

  Her comforting words appeared to do the trick. The absolute trust on his face tugged at her heart. Nodding, he grabbed his backpack and dashed out the door after his father. Sandra followed them, vowing to herself that, freaky signals or no freaky signals, she would see to it that her son was not disappointed.

  Besides, it was Joe’s birthday after all. He deserved a celebration—after he got the higher-ups at the plant to listen to him.

  * * *

  “Later, Dad!”

  Ford sprinted past the family car on his way to the bus stop. Seated behind the wheel, Joe waved distractedly at the boy, while wrapping up his call.

  “Good. Finally,” he said in Japanese. “Thank you.”

  Sandra slid into the passenger seat beside him. She clipped a “Janjira Power” ID badge to the lapel of her jacket and handed a matching badge to Joe.

  “He made you a sign, you know.”

  A sign? A pang of guilt stabbed Joe as he realized what she meant, and that he had been utterly oblivious to whatever she and Ford had cooked up for his birthday. Contrite, he put down his phone and looked over at his wife. He’d had no idea …

  “He worked so hard,” she said. “I think what I’m gonna do, I’m gonna come home early. I’ll take the car and pick him up and we can get a proper cake.”

  Joe was grateful that she was on top of this—and letting him off so easily. “I’m gonna practice being surprised all day. I promise.”

  To prove his sincerity, he generated his best “Holy Shit!” expression. His eyes bugged out and his jaw dropped as though he had just won the lottery. The effort teased a laugh from Sandra. He smirked back at her, enjoying the moment. Which couldn’t last, unfortunately. Not with the matter preying on his mind.

  “Look,” he said, “I need to know it’s not the sensors. I can’t call this meeting and look like the American maniac. We get in, don’t even come upstairs, just grab a team and head down to Level 5—do 5 and the co
olant cask—just check my sensors. Make sure they’re working.”

  “You’re not a maniac,” she assured him. “I mean, you are, just not about this.”

  He appreciated her effort to lighten the mood, but he had too much on his mind to joke around right now. “There’s got to be something we’re not thinking of.”

  “Happy birthday,” she said stubbornly.

  He turned toward her. An infectious smile penetrated the cloud hanging over him, and reminded him just how lucky he really was. The corners of his lips lifted.

  “I don’t know what you’re talking about,” he lied.

  She leaned forward and kissed him warmly on the lips. Despite all his worries and frustration, he responded to the kiss, keeping it going even as he fired up the ignition. They reluctantly disengaged as he pulled away from the curb and headed towards the plant, which loomed prominently on the horizon.

  His birthday would have to wait.

  * * *

  The Janjira Nuclear Power Plant perched above the coastline, dominating the skyline overlooking the Sea of Japan. Thick white plumes of steam vented from the plant’s cooling towers, while the reactors themselves were secured within three imposing structures of steel and concrete that had been built to withstand even a crashing 747. Adjoining buildings housed the turbines, generators, pumps, water tanks, storage units, machine shops, administrative offices, and other essentials. A row of transmission towers rose from the switchyard adjacent to the plant. High-voltage power lines transmitted freshly generated electricity to the nearby city and points beyond.

  After parking the car in the lot, Joe and Sandra hurried off on their respective tasks. Within minutes, Joe was marching briskly down a corridor, trailed by Stan Walsh, his best friend and partner in crime. Another transplanted American, Stan was a few years older than Joe, who was counting on Stan to back him up when they met with Hayato and the others. Joe gulped down black coffee on the run. “#1 DAD” was emblazoned on his mug, a title Joe doubted he was entitled to this morning.
