Chapter 1: The Great Escape (Again)

Hades sighed. Not just any sigh—the kind of deep, bone-weary exhale that only an immortal god dealing with an eternally hyperactive ghost nephew could manage. He pinched the bridge of his nose and glared at his palace guards.

"Say that again," he said, voice dangerously calm.

The nearest skeleton warrior trembled, despite not having a nervous system. "H-he's gone, my lord."

Hades closed his eyes. "And Cerberus?"

The skeleton hesitated. "Gone as well."

Hades opened his eyes, staring at the empty space where his favorite hellhound was supposed to be. There was nothing there.

"Again?" Hades growled.

Persephone, lounging nearby with a glass of nectar, didn't even look up. "You should really just accept that this is going to keep happening," she said cheerfully. "At least he didn't take the Helm of Darkness this time."

That was true, but it didn't make Hades feel any better.

He stood abruptly, his black robes swirling around him as he stomped toward his throne. "I swear, I'm putting up fences," he muttered. "Big ones. With spikes. And a warning sign—"

"But then Elysium will look like the Fields of Punishment," Persephone reminded him.

Hades groaned and slumped onto his throne. She was right, of course. He couldn't just turn the paradise of heroes into a supernatural prison. But seriously—how did an eight-year-old ghost and a three-headed hellhound keep escaping the literal Underworld? And more importantly… where had they gone this time?

Meanwhile, at Camp Half-Blood…

Chiron had seen many things in his thousands of years so this was not as surprising as it should be.

The questers—Percy Jackson, Annabeth Chase, and Grover Underwood—were standing frozen at the edge of camp, staring at the thing in front of them. Behind them, the rest of the campers were cautiously peeking out from behind buildings, gripping weapons, whispering in alarm.

It was a child. A little boy, no older than eight, with sea-green eyes and messy black hair. He was barefoot, wearing a loose tunic that looked like it belonged to Ancient Greece, and was grinning from ear to ear.

Next to him, taking up way too much space, was Cerberus. The actual, legendary, three-headed hellhound. Each massive head was panting happily, tongues lolling, as if they had just arrived for a fun little outing.

"Hi!" the boy chirped. "I'm Percy! This is my best friend, Cerberus."

Grover made a strangled noise. Annabeth's knife was already halfway out. Percy Jackson (the taller, mortal one) just blinked.

"Wait," the mortal Percy said. "You're also Percy?"

The little boy nodded enthusiastically. "Yup! I was Percy first! But I died, and now I'm a ghost! But I got bored, so I decided to visit! Also, Cerberus missed you."

The campers collectively took a step back as the massive hellhound wagged its three tails, shaking the ground.

Annabeth turned to Chiron. "What. The. Hades."

Chiron sighed, rubbing his temples. "Ah. So it's that time again."

Mount Olympus

Zeus stared at the scrying pool, his left eye twitching. "Him again?"

Athena pinched the bridge of her nose. "It appears so."

Apollo snickered. "Man, I love that kid. I mean, I wouldn't want him following me around, but it's hilarious when it's Hades' problem."

Hera crossed her arms. "Why is he Hades' problem? He's a child of Poseidon, isn't he?"

Poseidon, who had been silent until now, cleared his throat. "Technically."

Zeus whirled on him. "Technically?!"

Poseidon shrugged. "Well, he was my son, back when he was alive. But he's been a spirit for a long time, and he does live in the Underworld, so…" He waved a hand vaguely.

Ares snorted. "So what, Hades gets stuck with babysitting duty?"

"Seems fair," Hermes said cheerfully. "It is his realm."

Zeus growled, lightning crackling at his fingertips. "I do not have time for this. We are already dealing with the theft of my bolt, and now we have this nuisance running amok in the mortal world again?"

Aphrodite sighed dreamily. "I think he's adorable."

Zeus ignored her. "Send a message to Hades. Tell him to deal with his nephew."

Back at Camp Half-Blood

Little Percy giggled, swinging his legs as he sat on the Big House porch, completely oblivious to the chaos he'd caused.

"Are we going on an adventure?" he asked brightly.

The older Percy—who was still trying to process the fact that he apparently had a ghost twin—exchanged a look with Annabeth and Grover.

"I… guess?" he said hesitantly.

"Yay!" Little Percy cheered. "This is gonna be so much fun!"

Behind him, Cerberus let out a pleased woof that shook the trees.

From somewhere deep in the Underworld, Hades let out a long, tired groan.
