Summary
It's basically a bunch of Riordanverse characters in a collage setting with no demigod powers and shit. And NOBODY is dead, I can't deal with that. And it has some of my favorite rare ships that I really enjoy. Anyways I hope you enjoy it since my writing can be sucky at times, and most of it will be written at 2-5 am. Updates will not be consistent. And please be nice English is not my 1st language.

Summary
She’s a demigod who’s spent ten years dodging monsters and camp drama—no big deal. Now she’s back at Wayne Manor, trying to figure out how to be Bruce Wayne’s long lost daughter without turning the Batcave into a disaster zone. Juggling family secrets, ancient oaths, and a legacy that’s way too complicated, she’s ready to prove that saving the world (and surviving family dinners) is all in a day’s work—preferably with coffee, sarcasm, and maybe a few explosions.
OR where Marley Reed was once called Marlene Wayne and is one her way home after a decade of war to join a different battle: family time. She was coming home for the first time since running away after her brother's death, this time with extra luggage called trauma. She was ready to gaslight, gatekeep, and girlboss her way through avoiding the truth of where she’s been. Too bad the Gotham vigilantes aren’t buying it. They really just want to help, but it’s too complicated to tell them. Until it gets more complex, and the only way to make it out is to tell them.
Holy Hades, she needs a break.

Summary
Tim now stared at the papers in his hand with disbelieving eyes. Holy fuck, Bruce is going to kill me.
The buzzing of his phone broke through his thoughts, and for a moment, Tim considered flinging it across the room to shut it up. Then, apparently the phone had been so insistent and non-stop for the past few minutes, that Percy had begun to stir.
Good timing. As soon as Percy's eyes fluttered open, Tim shoved the marriage certificate and license in front of his face.
“Hey, remember last night?” Tim asked as he watched Percy groggily scanned over the certificate.
Tim waited patiently for the man's brain to catch up, watching him furrow his brows as he tried to read the written text over and over. Then, a good few minutes later, he dragged a hand down his face in defeat.
“I'm actually dyslexic,” Percy said, flatly. His eyes fluttered close again.
Tim wanted to shake him.
OR; Tim wasn't one for impulsive decisions, but Percy definitely was.

Summary
For Alexander Prince, life has been one long series of him trying to make his own place in the world. He knows how unforgiving it is, and the last thing he'll ever do is let this thing called reality break him. He'll survive, as he's always done: Alone.
But after being confronted by a vicious monster in disguise as someone he thought he knew, Alexander is forced to reconcile that his version of "reality" is all one big lie. Ancient gods with bad attitudes still exist. Anyone he sees could be some horrible nightmare out to kill him. And most frighteningly of all, a bunch of people want to be his friend now.
Apparently, he's a demigod, they say. A product of a relationship between an Olympian and a mortal. He's never met either one of his parents, so he can't exactly disprove that notion, but as he tries to adjust to this new life, one of those answers becomes clear. And it puts his life in mortal danger.
Alexander should not, by any rhyme or reason, exist. And unless he can figure out why this impossibility came to pass, he won't be alive for very much longer.
(Expect a monthly update until my other PJO work, The Other Heroes, concludes. Once it does, I'll fully devote my time to this story.)

Summary
“A man showed up.”
Percy frowned. “What do you mean, like an adult human man?”
“Exactly like an adult human man. He’s got greyer hair than you, looks like he might be in his fifties.”
Percy squinted and paused. “At camp? Is this another Tantalus situation?”
“Not that we can tell. He’s the new swords instructor. I don’t think he’s as good as you.”
“So if he’s not a spirit, did Chiron just like, pick up a mortal?”
“He says he’s a demigod.”
Percy stilled. “That’s impossible.”
“He’s suspicious, is what he is. Says his name is Quintus. Has a hellhound named Mrs. O’Leary. Was mildly shocked when we barely blinked at her. I think the top bet right now is that he’s actually you from the future.”
~
This are heating up in the demigod world as the titan army gathers. Clarisse is looking for something in the Maze, tensions are rising, and apparently there's a middle aged demigod running around that Percy's torn between obsessing over and hating on principle. No one knows who to trust, and a malevolent force is writhing beneath their feet...

Summary
Yeah, Drew fit most of the Aphrodite kids stereotypes, except one.
Drew was once one of those Aphrodite kids, a hopeless romantic and a romance centered person. But after Silena's betrayal, Drew began to wonder...
Wonder if true love was real, after all, the camp says Charles and Silena truly loved each other yet they both died.
Yet Silena still betrayed the camp, betrayed Charles.
Drew started to think that love was foolish and fake and for that she got punished.
Cursed to only be able to love and never be loved.
Her own mother punished her for thinking such unromantic thoughts.
She cursed Drew with the worst curse a child of Aphrodite can get, a curse of never having true love, never having any kind of romantic love.
So, when Rachel Dare confessed to Drew about her crush, she knew something was up.- Language:

Summary
Leo Valdez volunteers for the Hunger Games in place of his younger brother Harley. He has no idea what he's started.
Across the districts, Nico Di Angelo doesn't think before he volunteers for Bianca. His district isn't pleased.
Turns out, having two volunteers in a world in which volunteers are highly frowned upon probably won't end well. Unless they become the media's favorites, of course.
Still, the odds are in nobody's favor.

Summary
In his defence, Nico was curious. And he just so happened to also be tired, which is what led them to this situation.
How was he supposed to know that his failed experiments/anniversary gift would get him stranded in another universe with an Egyptian God/Magician/Both/I’m really not sure as his only company?
Things only get stranger when a creature riding a motorcycle that claims he's a hedgehog feels the need to look over them, to protect them from the government and a crazy scientist with artificial children.
In the meantime, Will is desperate to find his boyfriend, and already done with the bullshit they have gotten themselves into.
Shadow is not amused by this situation either, if you couldn't tell.

Summary
Basically a Percabeth AU set in college where it's "we become friends-fake dating-we build a LOT of trust-we fall for each other”. It's depressed. Even if it's a Percabeth fanfic it is also about mental health and it has a happy ending. That's what I can say.
Percy Jackson is just trying to make it through college without worrying his mother too much after what happened in high school.
Annabeth wants to escape her family and succeed in life.
Once they meet they realize that faking a relationship could help them accomplish their goals. -
