Chapter 1

We Wake Up In Topsy Turvey Land

Jason Grace honestly had no idea how it had happened.

Everything had been so right in the world. He had Piper by his side, Leo had come back- Nico had evidently been in charge of some sort of smack and greet? - and everything was right with the world. His best friend was back, all of them were happy, Reyna was actually talking to him again, the Camps were at peace, what could possibly go wrong?

Well, that's the thing.

That's a question a Demigod should never, ever, ask themselves.

Jason remembered going to sleep with Piper in his arms. They hadn't actually done anything- Jason really couldn't bring himself too with that creepy giant statue of his dad in the middle of his cabin, it was definitely a mood killer- but the pair of them did like sharing a bed.

After the wars, after the struggles, it was good to wake up wrapped around someone you love, and Jason Grace loved Piper McLean with all his heart.

Everything was right with the world.

Everything was perfect.

Until, it wasn't.

Jason woke up with a start. Groggily, he sat up, blinking at the sound of- explosions? It took less than a second for Jason's brain to process the information, for him to take in his surroundings, for his mind to come to several conclusions.

One, Piper was no longer at his side.

Two, he was no longer in Cabin One.

And, three, he was back at Camp Jupiter.

Jason sprung up from bed, shocked. How had he- no, it didn't matter. It didn't matter how Jason had magically transported to Camp Jupiter in the middle of the night, all that mattered was that he was here and Camp Jupiter was under attack.

Without a second though, Jason rummaged around for a weapon, anything, before his hands closed around a coin. Jason blinked. He could have sworn- another explosion shook the camp. No time.

The door was slammed open.

"Jason- What in Mars name, were you honestly sleeping through an attack?"

Jason froze.

One second.

Two.

Ivlivis spun in the air, a spear fell into Jason's hands, and Octavian found himself pinned to the wall, the sharp end at his throat.

"Preator, have you lost your min-"

"You died." Jason cooley interrupted. Octavian looked at him as if Jason had lost his mind. For a second, Jason believed he had before he continued, resisting the urge to snarl. "I was there. I watched you burn… No, impossible…" Jason began to mutter to himself, eyes shining with suspicion.

Octavian looked at him as if he were mad. And, for a second, Jason could have sworn there was a look of concern in the former Augur's eyes, but that had to be a trick of the light. Octavian had been a power hungry bastard. He had cared for nobody and nothing other than himself, the rest of the world be damned.

"Perhaps it was a dream. A sign from the Gods, something we are meant to stop," Octavian suggested. Jason snorted. Of course. Octavian was concerned. Concerned for his own survival, that is.

Another explosion shook the complex.

Jason considered.

For all he knew, this could be an illusion of the Mist. This could all be in his head. A God, a powerful Demigod like Hazel skilled in Mist Manipulation, hell, he might have managed to piss of Dionysus and this was all a mad hallucination.

"We have no time. The camp is under attack." Jason concluded, letting his speak drop before moving out the door without a second though.

Octavian stood still for a moment, scratching his chin.

Normally, this was something Octavian would have used to his advantage.

A Praetor of Rome, unable to tell reality from dream?

However, on the other hand…

Octavian was no fool. They needed every man woman and child if they hoped to survive. A mentally unstable Jason was a threat to them all. Octavian may be a power hungry bastard, but he was a patriotic power hungry bastard. Narrowing his eyes, the Legacy contemplated his next move.

The son of Jupiter decided to pay the skinny Augur no mind. He'd deal with Octavian's apparent survival later. Right now, he had a duty to fulfill. Jason Grace may no longer be Praetor of Camp Jupiter, but this is where he had been raised. This place had been his home for so many years. Jason would be damned if he let it fall on his watch.

However, when Jason finally made his way outside… He seriously wished he hadn't. Jason could not believe his eyes. This had to a lie. Nightmare. This was a nightmare. He'd pissed off Somnia. That had to be it.

Because this?

This could not be real.

The world around him could not be the true reality. This had to be a lie. A farce. A deception. This wasn't real. None of this was real. None of this could be real.

Because, let's face it.

In what world would the Argo II blast away at the border of Camp Jupiter make any sense at all? Okay, that had technically happened the first time around too, but that been due to possession.

Now, unless there was an army of Eidolons, this was no possession.

This was not real.

This could not be real.

Please, let him wake up. Let this all be a dream, a nightmare, hell, Jason would even take a Demigod vision as long as it meant he'd get a chance to prevent it from happening.

Because, there, above in the sky, was the Argo II.

And it was raining fire down upon Camp Jupiter.

"Jason! Jason!"

Jason's mouth snapped shut. No more gaping like an idiot. He barely even acknowledged Reyna as she ran up to him, pulling uselessly on his sleeve. Jason's eyes were still blankly transfixed on a ship that he distinctly remembered had exploded. Okay, so Leo was on repairs, but he hadn't finished yet. Perhaps someone had hijacked the Argo II despite it not being finished the day before and did it faster than Leo could have? Unlikely, sure, but the alternative… Yeah, that had to be it. Someone had hijacked the Argo II and-

"Attention, Roman Demigods." Jason knew that voice. Dread pooled into the pit of his stomachs. No… No…. No…

There, at the helm of the ship, stood a boy Jason knew well.

Their bro competitions were legendary.

"The Era of Old has come to an end! The Gods Have fallen, Olympus is ours, and this is a dawning of a New Age, a Golden Age for mankind! Come, brothers and sisters, and kneel before the Lord Saturn! The Age of Titans begins again!"

No… No… No…

"Jason, what the hell is happening! Why is Percy leading an army against us! And, how is Octavian still alive!"

Jason's eyes snapped towards her. With shock, Jason realized one thing. Reyna remembered. A dark feeling built into the pit of his stomach.

Reyna remembered.

Reyna remembered.

She remembered.

For her to remember a world that Jason knew as reality, that meant…

"Oh Gods… This… This is real?"

Rachel Elizabeth Dare had no idea how it happened.

She, of all people, could feel it.

The change in the flow.

The breaking of destiny.

A change, echoing across time and space.

She felt when the world flipped, when everything she knew, everything she loved, everything she cherished faded into a dark new reality.

There was perhaps only one positive to that.

Rachel awoke in a Camp Half Blood.

She didn't know how she knew. However, there were things she did know, instinctively, as she shuddered awake. Clutching at the sheets, Rachel managed to get control of the tremors that shook at her before looking around.

This was her cave.

Only, of course, it was now just a cave.

Closing her eyes, Rachel felt the world.

Something was gone.

Something was missing.

Something that should be and now wasn't.

A small detail had been changed. The flow was no longer the same.

Because of that… Kronos had won. Someone had actually managed to change the flow of time. Someone had actually managed to alter the reality they all knew. Someone… But how?

HOW!?

Even Kronos himself couldn't alter the timeline, and he was the Titan Lord of Time!

Rachel stood and made her way out to the Camp.

It was only then that she realized, her eyes gazing forward…

There was really only one way Kronos would spare Camp Half Blood. There was only one reality where Kronos won and Camp Half Blood still miraculously stood. There could only be one way.

Camp Half Blood was… Was under his control.

Rachel instantly quelled her thoughts. Gods could be alerted by words alone. Rachel had been the host of the Oracle of Delphi. With a start, Rachel realized the Oracle was no longer with her. She was gone. Still, Rachel's thoughts were not a safe place, especially in a world where Kronos ruled.

She had to get out.

She had to run.

But where!?

The world was under Kronus' command. No doubt the Titan Lord was quelling rebellions all over the Globe, but it would not matter. With a start, Rachel extended her senses and came to a terrible feeling of dread.

The humans had fought back…

They'd aimed nuclear weapons at Greece, shattering the ancient hold of the Olympians. That was the problem though… They had shattered…

"Shit," Rachel cursed, glancing down at the Camp. Even now, she could see small activity.

"Dare!"

Rachel jumped, spun and reflexively lept back.

Clarisse just raised a single eyebrow in confusion before the daughter of Ares shrugged it off. She couldn't be bothered with Rachel's weirdness.

Wait.

Daughter of Ares…

"Clarisse?"

Clarisse La Rue would never kneel before Kronos. She was proud. She was stubborn. She was a fighter. Clarisse would have gone down fighting, snarling like a hellhound, literally incapable of lifting a weapon and still fighting on with her teeth. If Clarisse was here, that meant one thing.

"Kronos doesn't control the camp…"

Rachel hadn't realized she'd spoken out loud until she was slammed the rock wall by Clarisse. Rachel hissed as the sharp earth dug into her back.

"Of course that filthy bastard doesn't control this camp! We are the last stance! We are the Resistance! I don't know what you've been smoking in that cave of yours, Dare, but if you mention his name again-"

"Sorry, sorry!" Rachel exclaimed. However, that did bring to question one very important thing. Rachel glanced down at the camp. Then, her eyes darted to the side, towards the rest of New York. Though she couldn't see it from here, Rachel had no doubt that Olympus was were Kronos would make his new throne, upon the ruins of his children. They were so close to him… Yet… Yet… Rachel's eyes locked with Clarisse's.

"How have we not been overrun?"

Clarisse stared at her for several seconds. Then, at last, the daughter of Ares let her go, laughing long and hard.

"Clarisse?" Rachel asked as the daughter of Ares chuckled away on the border of hysteria.

"Our seer is going mad! Great, just what we need!"

"Clarisse!" Rachel snapped.

Clarisse, however, was not listening. Instead, she kept laughing away, at the edge of hysteria. Rachel was frightened. Any place that could do that to Clarisse, of all people… This was not a world she wanted to live in. This was not her world.

"CLARISSE!" Rachel thundered, slapping the daughter of Ares. That stopped her short. For a second, Rachel feared for her life. Clarisse wasn't exactly the calmest of Demigods. At the very least, Rachel expected a smack in return. Instead, Clarisse sighed, looked at her, and oddly enough…

"Thanks. Needed that."

Rachel took Clarisse's hands in her own and looked into the eyes of the daughter of Ares.

"Clarisse… Please… Tell me what happened. Tell me how Camp Half-Blood is still here. Please…"

"You really don't remember?"

Rachel shook her head. No, she really didn't remember… Because this world was not hers. Rachel could feel it. Every sense in her screamed it. This was not her world, but at the same time, it was. Someone had taken what she new and flipped it all around.

An inverted world.

Clarisse now looked like she wanted to throttle Rachel. Rachel winced at even the thought. Clarisse had a really rough swing. While Rachel had never been on the receiving end of said swing, she'd seen it in action.

Then, Clarisse let out a breath and the anger in her eyes suddenly faded. Rachel wished it would come back. That defeated look… It was terrifying.

"Come with me," Clarisse said, turning her back. Without even bothering to check if Rachel was following, she made her way down to the camp. With nothing better to do, Rachel followed.
