Harry reads Percy Jackson and the Lightning Thief with a few others-what will their reactions be when they read the book? As their knowledge builds up, the wizards prepare to meet the demigods.

Harry is a wizard, and many secrets are kept hidden away from him-but not this one. When Voldemort fails to kill the two twins, Dumbledore realizes what to do. Harry soon realizes that HE himself is a demigod, and his long lost sister is attending Camp Half Blood. Half wizard, Half Demigod-what will he do?

Harry Potter/ Heroes of Olympus crossover. While there are many such stories, few (none) have so far been finished. I wanted to see what I could do with the seven and the Golden Trio. This is my first attempt at fanfiction, so please be gentle! Rated T just in case. DISCONTINUED!

Nothing's easy when you're a demigod or magical, but what happens when you mix the two? Meet Harry and Percy Potter-Jackson, two magic-wielding demigod twins! Who said exploring one world was hard, try three! But that's only half the fun!

Percy Jackson is a weathered demigod who arrives at London with hopes to flee his heavy titles for once. The two meet at one strange pub while drinking. They spend a night together in the most spontaneous manner. The Daily Prophet paparazzi makes a story out of it. [T to be safe]

Percy has just been told that he's Voldemort's grandson. What will happen when he's thrown into a new world, and his life becomes even more hectic? Please review.I want to know what I'm doing wrong, so I can write the best story possible for you guys. Disclaimer: it all belongs to Rick Riordan and JK Rowling except the plot

Read as Percy and the rest of the seven complete their journey through Hogwarts. AU. Percabeth, Jasper, Frazel, Caleo and Solangelo.

If you're Percy jacskon life is hard.

A person's destiny is never set in stone, Harry now knows that better than anyone. After all, his destiny has been completely turned on its head by the actions of both his mother and a capricious goddess. Whether this is for good or bad is yet to be seen, either way Harry's life has been set on a new course, and he for one could not be happier about it.

Sorry I am rubbish at summaries, basically Harry Potter is taken by two higher beings and is then sent to different universes and times to keep the balance between light and dark stable, eventually he winds up being born in Sparta (yes, that Sparta but he wont be wearing nappies and kicking people down holes) and he confronts demi gods, monsters and a certain goddess

For Percy Jackson, life was good. No more wars, a great family, and the gods weren't blaming him for anything he didn't do. But all of that changes when he finds himself as some other kid, with some hairy guy claiming Percy's name is Harry Potter, and he's a wizard. (ABANDONED, UP FOR ADOPTION. PM FOR DETAILS)

Dos mundos que se entrecruzan más de lo que parece; uno de ellos olvidado por la mayoría del otro. Una profecía mal interpretada. Y un joven , que deberá descubrir su misión antes de culminarla. Harry es un semidiós pero al mismo tiempo un lejano legado de otro por parte de padre.
