Breathe With Me (One, Two, Three) by Lukas Avier reviews
Dean didn't know what he did wrong. Why did Sam and his dad have to leave him? He was hunting on his own now and he was down-spiraling each and every time his calls disconnected. Just when he's at the end of his rope, a waiter barges in with his accidental insults and snarky attitude. But the waiter seems to be hiding something and it looks like secrets hang heavy on his shoulders.

Dark Knights in Gotham City by Firelord Mel reviews
A new student is coming to Gotham Academy. Someone who goes by the name of Nico di Angelo. Starts off like your average high-school story fanfic, but will turn into something else as the story progresses. Full summary inside.

Sulting by oxXDaughterOfAthenaXxo reviews

When Leo and Calypso try to get back to Camp Half-Blood they get captured by the Team. Quick-wit and humor don't seem to be getting him out of this situation.

I, The Sea Spy by ThePenNerd reviews
Perseus Jackson is many things. A hero, a swordsman, and a boyfriend. But he is definitely NOT a spy. But Percy is being sent to spy on playboy billionaire philanthropist Tony Stark anyway. All he has to do is sneak on his computer. What could possibly go wrong? Rated T due to paranoia.
