The Mark of Athena (The Heroes of Olympus, Book Three) Read online

  “Oh, gods,” Hazel muttered. “Nico…”

  Percy stared at his jelly donut. He had a rocky history with Nico di Angelo. The guy had once tricked him into visiting Hades’s palace, and Percy had ended up in a cell. But most of the time, Nico sided with the good guys. He certainly didn’t deserve slow suffocation in a bronze jar, and Percy couldn’t stand seeing Hazel in pain.

  “We’ll rescue him,” he promised her. “We have to. The prophecy says he holds the key to endless death.”

  “That’s right,” Piper said encouragingly. “Hazel, your brother went searching for the Doors of Death in the Underworld, right? He must’ve found them.”

  “He can tell us where the doors are,” Percy said, “and how to close them.”

  Hazel took a deep breath. “Yes. Good.”

  “Uh…” Leo shifted in his chair. “One thing. The giants are expecting us to do this, right? So we’re walking into a trap?”

  Hazel looked at Leo like he’d made a rude gesture. “We have no choice!”

  “Don’t get me wrong, Hazel. It’s just that your brother, Nico… he knew about both camps, right?”

  “Well, yes,” Hazel said.

  “He’s been going back and forth,” Leo said, “and he didn’t tell either side.”

  Jason sat forward, his expression grim. “You’re wondering if we can trust the guy. So am I.”

  Hazel shot to her feet. “I don’t believe this. He’s my brother. He brought me back from the Underworld, and you don’t want to help him?”

  Frank put his hand on her shoulder. “Nobody’s saying that.” He glared at Leo. “Nobody had better be saying that.”

  Leo blinked. “Look, guys. All I mean is—”

  “Hazel,” Jason said. “Leo is raising a fair point. I remember Nico from Camp Jupiter. Now I find out he also visited Camp Half-Blood. That does strike me as… well, a little shady. Do we really know where his loyalties lie? We just have to be careful.”

  Hazel’s arms shook. A silver platter zoomed toward her and hit the wall to her left, splattering scrambled eggs. “You… the great Jason Grace… the praetor I looked up to. You were supposed to be so fair, such a good leader. And now you…” Hazel stomped her foot and stormed out of the mess hall.

  “Hazel!” Leo called after her. “Ah, jeez. I should—”

  “You’ve done enough,” Frank growled. He got up to follow her, but Piper gestured for him to wait.

  “Give her time,” Piper advised. Then she frowned at Leo and Jason. “You guys, that was pretty cold.”

  Jason looked shocked. “Cold? I’m just being cautious!”

  “Her brother is dying,” Piper said.

  “I’ll go talk to her,” Frank insisted.

  “No,” Piper said. “Let her cool down first. Trust me on this. I’ll go check on her in a few minutes.”

  “But…” Frank huffed like an irritated bear. “Fine. I’ll wait.”

  From up above came a whirring sound like a large drill.

  “That’s Festus,” Leo said. “I’ve got him on autopilot, but we must be nearing Atlanta. I’ll have to get up there… uh, assuming we know where to land.”

  Everyone turned to Percy.

  Jason raised an eyebrow. “You’re Captain Salt Water. Any ideas from the expert?”

  Was that resentment in his voice? Percy wondered if Jason was secretly miffed about the duel in Kansas. Jason had joked about it, but Percy figured that they both harbored a little grudge. You couldn’t put two demigods in a fight and not have them wonder who was stronger.

  “I’m not sure,” he admitted. “Somewhere central, high up so we can get a good view of the city. Maybe a park with some woods? We don’t want to land a warship in the middle of downtown. I doubt even the Mist could cover up something that huge.”

  Leo nodded. “On it.” He raced for the stairs.

  Frank settled back in his chair uneasily. Percy felt bad for him. On the trip to Alaska, he had watched Hazel and Frank grow close. He knew how protective Frank felt toward her. He also noticed the baleful look Frank was giving Leo. He decided it might be a good idea to get Frank off the ship for a while.

  “When we land, I’ll scout around in Atlanta,” Percy said. “Frank, I could use your help.”

  “You mean turn into a dragon again? Honestly, Percy, I don’t want to spend the whole quest being everyone’s flying taxi.”

  “No,” Percy said. “I want you with me because you’ve got the blood of Poseidon. Maybe you can help me figure out where to find salt water. Besides, you’re good in a fight.”

  That seemed to make Frank feel a little better. “Sure. I guess.”

  “Great,” Percy said. “We should take one more. Annabeth—”

  “Oh, no!” Coach Hedge barked. “Young lady, you are grounded.”

  Annabeth stared at him like he was speaking a foreign language. “Excuse me?”

  “You and Jackson are not going anywhere together!” Hedge insisted. He glared at Percy, daring him to mouth off. “I’ll go with Frank and Mr. Sneaky Jackson. The rest of you guard the ship and make sure Annabeth doesn’t break any more rules!”

  Wonderful, Percy thought. A boys’ day out with Frank and a bloodthirsty satyr, to find salt water in a landlocked city.

  “This,” he said, “is going to be so much fun.”

  PERCY CLIMBED OUT ON DECK AND SAID, “WOW.”

  They had landed near the summit of a forested hill. A complex of white buildings, like a museum or a university, nestled in a grove of pines to the left. Below them spread the city of Atlanta—a cluster of brown and silver downtown skyscrapers two miles away, rising from what looked like an endless flat sprawl of highways, railroad tracks, houses, and green swathes of forest.

  “Ah, lovely spot.” Coach Hedge inhaled the morning air. “Good choice, Valdez.”

  Leo shrugged. “I just picked a tall hill. That’s a presidential library or something over there. At least that’s what Festus says.”

  “I don’t know about that!” Hedge barked. “But do you realize what happened on this hill? Frank Zhang, you should know!”

  Frank flinched. “I should?”

  “A son of Ares stood here!” Hedge cried indignantly.

  “I’m Roman…so Mars, actually.”

  “Whatever! Famous spot in the American Civil War!”

  “I’m Canadian, actually.”

  “Whatever! General Sherman, Union leader. He stood on this hill watching the city of Atlanta burn. Cut a path of destruction all the way from here to the sea. Burning, looting, pillaging—now there was a demigod!”

  Frank inched away from the satyr. “Uh, okay.”

  Percy didn’t care much about history, but he wondered whether landing here was a bad omen. He’d heard that most human civil wars started as fights between Greek and Roman demigods. Now they were standing on the site of one such battle. The entire city below them had been leveled on orders of a child of Ares.

  Percy could imagine some of the kids at Camp Half-Blood giving such a command. Clarisse La Rue, for instance, wouldn’t hesitate. But he couldn’t imagine Frank being so harsh.

  “Anyway,” Percy said, “let’s try not to burn down the city this time.”

  The coach looked disappointed. “All right. But where to?”

  Percy pointed toward downtown. “When in doubt, start in the middle.”

  Catching a ride there was easier than they thought. The three of them headed to the presidential library—which turned out to be the Carter Center—and asked the staff if they could call a taxi or give them directions to the nearest bus stop. Percy could have summoned Blackjack, but he was reluctant to ask the pegasus for help so soon after their last disaster. Frank didn’t want to polymorph into anything. And besides, Percy was kind of hoping to travel like a regular mortal for a change.

  One of the librarians, whose name was Esther, insisted on driving them personally. She was so nice about it, Percy thought she must be a monster in disguise; but Hedge p
ulled him aside and assured him that Esther smelled like a normal human.

  “With a hint of potpourri,” he said. “Cloves. Rose petals. Tasty!”

  They piled into Esther’s big black Cadillac and drove toward downtown. Esther was so tiny, she could barely see over the steering wheel; but that didn’t seem to bother her. She muscled her car through traffic while regaling them with stories about the crazy families of Atlanta—the old plantation owners, the founders of Coca-Cola, the sports stars, and the CNN news people. She sounded so knowledgeable that Percy decided to try his luck.

  “Uh, so, Esther,” he said, “here’s a hard question for you. Salt water in Atlanta. What’s the first thing that comes to mind?”

  The old lady chuckled. “Oh, sugar. That’s easy. Whale sharks!”

  Frank and Percy exchanged looks.

  “Whale sharks?” Frank asked nervously. “You have those in Atlanta?”

  “At the aquarium, sugar,” Esther said. “Very famous! Right downtown. Is that where you wanted to go?”

  An aquarium. Percy considered that. He didn’t know what an Ancient Greek sea god would be doing at a Georgia aquarium, but he didn’t have any better ideas.

  “Yes,” Percy said. “That’s where we’re going.”

  Esther dropped them at the main entrance, where a line was already forming. She insisted on giving them her cell phone number for emergencies, money for a taxi ride back to the Carter Center, and a jar of homemade peach preserves, which for some reason she kept in a box in her trunk. Frank stuck the jar in his backpack and thanked Esther, who had already switched from calling him sugar to son.

  As she drove away, Frank said, “Are all people in Atlanta that nice?”

  Hedge grunted. “Hope not. I can’t fight them if they’re nice. Let’s go beat up some whale sharks. They sound dangerous!”

  It hadn’t occurred to Percy that they might have to pay admission, or stand in line behind a bunch of families and kids from summer camps.

  Looking at the elementary schoolers in their colorful T-shirts from various day camps, Percy felt a twinge of sadness. He should be at Camp Half-Blood right now, settling into his cabin for the summer, teaching sword-fighting lessons in the arena, planning pranks on the other counselors. These kids had no idea just how crazy a summer camp could be.

  He sighed. “Well, I guess we wait in line. Anybody have money?”

  Frank checked his pockets. “Three denarii from Camp Jupiter. Five dollars Canadian.”

  Hedge patted his gym shorts and pulled out what he found. “Three quarters, two dimes, a rubber band and—score! A piece of celery.”

  He started munching on the celery, eyeing the change and the rubber band like they might be next.

  “Great,” Percy said. His own pockets were empty except for his pen/sword, Riptide. He was pondering whether or not they could sneak in somehow, when a woman in a blue-and-green Georgia Aquarium shirt came up to them, smiling brightly.

  “Ah, VIP visitors!” She had perky dimpled cheeks, thick-framed glasses, braces, and frizzy black hair pulled to the sides in pigtails, so that even though she was probably in her late twenties, she looked like a schoolgirl nerd—sort of cute, but sort of odd. Along with her Georgia Aquarium polo shirt, she wore dark slacks and black sneakers, and she bounced on the balls of her feet like she simply couldn’t contain her energy. Her name tag read KATE.

  “You have your payment, I see,” she said. “Excellent!”

  “What?” Percy asked.

  Kate scooped the three denarii out of Frank’s hand. “Yes, that’s fine. Right this way!”

  She spun and trotted off toward the main entrance.

  Percy looked at Coach Hedge and Frank. “A trap?”

  “Probably,” Frank said.

  “She’s not mortal,” Hedge said, sniffing the air. “Probably some sort of goat-eating, demigod-destroying fiend from Tartarus.”

  “No doubt,” Percy agreed.

  “Awesome.” Hedge grinned. “Let’s go.”

  Kate got them past the ticket queue and into the aquarium with no problem.

  “Right this way.” Kate grinned at Percy. “It’s a wonderful exhibit. You won’t be disappointed. So rare we get VIPs.”

  “Uh, you mean demigods?” Frank asked.

  Kate winked at him impishly and put a finger to her mouth. “So over here is the cold-water experience, with your penguins and beluga whales and whatnot. And over there…well, those are some fish, obviously.”

  For an aquarium worker, she didn’t seem to know much or care much about the smaller fish. They passed one huge tank full of tropical species, and when Frank pointed to a particular fish and asked what it was, Kate said, “Oh, those are the yellow ones.”

  They passed the gift shop. Frank slowed down to check out a clearance table with clothes and toys.

  “Take what you want,” Kate told him.

  Frank blinked. “Really?”

  “Of course! You’re a VIP!”

  Frank hesitated. Then he stuffed some T-shirts in his backpack.

  “Dude,” Percy said, “what are you doing?”

  “She said I could,” Frank whispered. “Besides, I need more clothes. I didn’t pack for a long trip!”

  He added a snow globe to his stash, which didn’t seem like clothing to Percy. Then Frank picked up a braided cylinder about the size of a candy bar.

  He squinted at it. “What is—?”

  “Chinese handcuffs,” Percy said.

  Frank, who was Chinese Canadian, looked offended. “How is this Chinese?”

  “I don’t know,” Percy said. “That’s just what it’s called. It’s like a gag gift.”

  “Come along, boys!” Kate called from across the hall.

  “I’ll show you later,” Percy promised.

  Frank stuffed the handcuffs in his backpack, and they kept walking.

  They passed through an acrylic tunnel. Fish swam over their heads, and Percy felt irrational panic building in his throat.

  This is dumb, he told himself. I’ve been underwater a million times. And I’m not even in the water.

  The real threat was Kate, he reminded himself. Hedge had already detected that she wasn’t human. Any minute she might turn into some horrible creature and attack them. Unfortunately, Percy didn’t see much choice but to play along with her VIP tour until they could find the sea god Phorcys, even if they were walking deeper into a trap.

  They emerged in a viewing room awash with blue light. On the other side of a glass wall was the biggest aquarium tank Percy had ever seen. Cruising in circles were dozens of huge fish, including two spotted sharks, each twice Percy’s size. They were fat and slow, with open mouths and no teeth.

  “Whale sharks,” Coach Hedge growled. “Now we shall battle to the death!”

  Kate giggled. “Silly satyr. Whale sharks are peaceful. They only eat plankton.”

  Percy scowled. He wondered how Kate knew the coach was a satyr. Hedge was wearing pants and specially fitted shoes over his hooves, like satyrs usually did to blend in with mortals. His baseball cap covered his horns. The more Kate giggled and acted friendly, the more Percy didn’t like her; but Coach Hedge didn’t seem fazed.

  “Peaceful sharks?” the coach said with disgust. “What’s the point of that?”

  Frank read the plaque next to the tank. “The only whale sharks in captivity in the world,” he mused. “That’s kind of amazing.”

  “Yes, and these are small,” Kate said. “You should see some of my other babies out in the wild.”

  “Your babies?” Frank asked.

  Judging from the wicked glint in Kate’s eyes, Percy was pretty sure he didn’t want to meet Kate’s babies. He decided it was time to get to the point. He didn’t want to go any farther into this aquarium than he had to.

  “So, Kate,” he said, “we’re looking for a guy…I mean a god, named Phorcys. Would you happen to know him?”

  Kate snorted. “Know him? He’s my brother. That’s where we�
�re going, sillies. The real exhibits are right through here.”

  She gestured at the far wall. The solid black surface rippled, and another tunnel appeared, leading through a luminous purple tank.

  Kate strolled inside. The last thing Percy wanted to do was follow, but if Phorcys was really on the other side, and if he had information that would help their quest…Percy took a deep breath and followed his friends into the tunnel.

  As soon as they entered, Coach Hedge whistled. “Now that’s interesting.”

  Gliding above them were multicolored jellyfish the size of trash cans, each with hundreds of tentacles that looked like silky barbed wire. One jellyfish had a paralyzed ten-foot-long swordfish tangled in its grasp. The jellyfish slowly wrapped its tendrils tighter and tighter around its prey.

  Kate beamed at Coach Hedge. “You see? Forget the whale sharks! And there’s much more.”

  Kate led them into an even larger chamber, lined with more aquariums. On one wall, a glowing red sign proclaimed: DEATH IN THE DEEP SEAS! Sponsored by Monster Donut.

  Percy had to read the sign twice because of his dyslexia, and then twice more to let the message sink in. “Monster Donut?”

  “Oh, yes,” Kate said. “One of our corporate sponsors.”

  Percy gulped. His last experience with Monster Donut hadn’t been pleasant. It had involved acid-spitting serpent heads, much screaming, and a cannon.

  In one aquarium, a dozen hippocampi—horses with the tails of fish—drifted aimlessly. Percy had seen many hippocampi in the wild. He’d even ridden a few; but he had never seen any in an aquarium. He tried to speak with them, but they just floated around, occasionally bonking against the glass. Their minds seemed addled.

  “This isn’t right,” Percy muttered.

  He turned and saw something even worse. At the bottom of a smaller tank, two Nereids—female sea spirits—sat cross-legged, facing each other, playing a game of Go Fish. They looked incredibly bored. Their long green hair floated listlessly around their faces. Their eyes were half closed.
