Chapter 1

The day started out like any other day. Then again, most life-changing days did.

Percy woke up about half an hour late, kicked some junk under the bed, and wished for the gazillionth time that Tyson were there to pick up after him. He washed up, attempted halfheartedly to get his jet-black hair to lie down flat (fail) and shrugged on his cleanest orange Camp shirt and jeans. Grabbing his camp beads and Riptide, he slipped on the first pair of sneakers he saw and poked his head out of Cabin Three, the smooth shells imbedded in the rough gray stone feeling cool under his fingers.

Normal.

He had learned long ago that the way to get away with sleeping in at Camp Half-Blood was to slip in when everyone was changing activities. This meant that he had thirty minutes left until the current activity was over and the next began. Percy currently was supposed to be practicing swordplay and defense (taught by Clarisse-blech) until 10:00, a class in which he never did anything, anyways. He supposed it was unfair to unleash an invulnerable and soaking wet son of Poseidon on some perfectly innocent (yeah, and empousai were Girl Scouts) Ares campers. Still, how did Chiron expect him to pass up a chance to beat up Clar- instruct campers with one-on-one?

Usually, Percy wasted the time away by sneaking to the canoe lake. However, this also involved passing the showers, and it was just his luck that a certain blonde daughter of Athena was coming out at that moment, her curly blonde hair damp and her Camp-shirt-and-jeans uniform fresh.

The son of Poseidon tried to slip behind a pack of gossiping Aphrodite kids, who skillfully ignored him. Unfortunately for him, Annabeth saw him first, and popped up behind him just when he had thought he had lost her.

"Seaweed Brain!" she hissed, making Percy jump. Her startling gray eyes had a storm brewing. Percy gulped. She could somehow be beautiful and terrifying at the same time.

"Annabeth!" he exclaimed nervously. "I…didn't see you coming."

He was a pathetic liar, and they both knew it.

"I've been looking everywhere for you!" she snarled, looking ready to go Amazon on him. "Why aren't you at-"

At that exact moment, the familiar wail of a conch shell being blown signaled that the camp was under attack. Percy let out a sigh of relief. So maybe Tyche didn't have it out for him, after all. Of course, a monster attack was hardly lucky, but anything was better than facing an angry girlfriend, Curse of Achilles or not.

"We're finishing this conversation," Annabeth seethed, her eyes fierce and narrowed. The storms upgraded to hurricanes.

"Sure thing," Percy agreed readily, before sprinting to defend the borders. Mentally he added, Not.

Still normal. Monsters, furious at the fall of Kronos, were attacking the demigod's home almost every day at this point. And Annabeth was always scary when she was ticked off.

Percy began hastily strapping on the armor that a son of Hephaestus shoved in his face, before remembering that he didn't need it and chucking it at someone else. He let himself be swept away by the flow of campers, then noticed where they were heading. Usually monsters came charging out of the woods, perhaps by the armory, arena, stables, or mess hall. But he was going in the opposite direction, towards Half-Blood Hill. That meant something was going on near the entrance…and yet, no monster could enter the magical boundaries that cut off the camp from the mortal world. To the extent of Percy's knowledge, the Golden Fleece was keeping Thalia's Pine perfectly healthy, so the camp's borders should have been holding off any trespassers with ease. The only time that he could recall the boundaries falling was…

…When the Titans were in power. But Percy refused to believe that the older siblings of the gods had risen. Just refused. So what could be invading from the outside world? Maybe there's a guy giving away free magic swords. Or maybe the Nine Muses are there, signing autographs, Percy pleaded mentally. Please let it be free weapons.

Any remote hope of fighting a normal enemy (by demigod standards, that it) was brutally slaughtered when Percy saw the dragon hovering in the sky. Except it wasn't a dragon, or even a drakon. Firstly, the beast was huge. Even bigger than the Lydian drakon that Kronos had unleashed during the war, only to have it killed by a vengeful Clarisse. Second, its scales were unlike any described in the ancient book of monsters—dazzling shades of indigo, cerulean, and azure, like shards of gemstones. And finally, it had a Rider—a man decked out in rich but battered armor, his profile princely, but the way he held his blade that of a seasoned warrior.

The dragon reared its gleaming head, then unleashed an earthshaking roar that the Nemean Lion would have been proud of. A wave of blue fire spurted from its jaws, charring a line in the no-man's-land between it and the mob of campers that had almost reached it. The boundaries must have been partially functional, because the dancing flames wouldn't ignite. The blast hit no one, but left the defenders wary—a warning.

Definitely not normal.

Author's Note: I'm pretty new to fanfiction, so this story probably isn't very good. I'm trying, though! Also, this being my first story and stuff, I will worship you forever if you review with any typos, criticism, or whatever.
