Love is all "Percabeth" (and a bit lot of smut inside)

Because of a box of crayons, Percy and Annabeth are best friends for life. They share their food, their secrets, even each other's first kiss. All of a sudden, Percy's move causes their fairy tale friendship to splinter and rain clouds to appear. But when the green-eyed boy comes back, will everything remain back to the way it was? Percabeth. AU. by connorstoll

Percy is confused. Between late night phone calls, an almost kiss, and a literal punch in the face, he has no idea what Annabeth wants from him. The cute redhead paying all this attention to him hasn't helped matters, either. Annabeth is tired. She's been trying to ignore her feelings for way too long. But amidst the unrequited love, she's got too much on her plate. She doesn't know how much longer she can keep it up. They've been best friends forever. They're always there for one another... so what happens when one of them starts dating somebody else? Is jealousy justified if they're just friends? High school AU, lots of Solangelo! Rated M for some sour scenes (;

"Percy?" "Hmm?" "We're going to be friends for ever... right?" she asked hopefully, not letting the anxious look come across her face. "Of course." Percy smiled easily. At that moment, it was almost as if fate was chuckling darkly at them. Two kids in a rowboat dreaming of the unknown future. The inky ominous future that would tear them apart and fiddle with their heart strings. AU by Average Canadian

I've seen some of PJO and Avengers crossovers where Percy is Tony's assistant, but I was like, what if it was Nico? Because I love Nico and can never find enough fanfics about him. Pjo is aged up several years, they're adults now. Nico was annoyed. This isn't uncommon, seeing as he has to put up with annoying friends and terrified campers on a daily basis. However, neither of those were the reason for his annoyance, which was unusual. You see, after the Seven all went on with their lives, as one does, Nico didn't know what in Zeus's nose hair to do with his life. Sure, still had friends at Camp, but they had lives and goals. And yes, there's Will, but he can't just have him as his only reason to live, plus he also has a life and a goal as to what to do with it (Medical School). Nico does not. Other than his new job, he has no idea what to do with his life. However, after a video of a camper fighting a hellhound is released online, his boss and his friends start getting too nosy for their own good. Will Nico be able to keep his secret from the government, or will it all go wrong? Tony is interested. It's not very often someone can tell him what to do, and he ACTUALLY does it. So yes, he was very interested in his new assistant Pepper hired. What is it that makes Nico Di Angelo so special that Tony freaking Stark listens to him? And why does he have a sword?!
