This is a story I also have on Quotev under the same name and username, and I was going to post it on here at some point so I decided on a whim to do it now instead of later. Summary: What would happen if Percy Jackson and Harry Potter were twins?? What would happen if on the night Voldemort attacked the Potters and became a wraith, Dumbledore separated the twins, giving Harry to the Dursleys while shipping Percy off to a supposed squib by the name of Sally Jackson?? What would happen if they met up at Hogwarts, knowing that the other existed and had already formed a deep bond?? Well, let's just say that Dumbledore isn't getting the brash, ignorant Boy-Who-Lived Harry was in canon, because now, Percy comes in and does what he does best; he messes with Fate, kicks butt, and pulls off death-defying moves to protect his friends and family!!

The Dark Lord had a grandchild that no one knew about. This grandchild had a story of their own from a totally different world. This grandchild was Percy Jackson, the savior of Olympus. Takes place during The Half-Blood Prince and after the Blood of Olympus. Keep reading to find out more.

Gaea has been defeated, Leo has returned with Calypso, and everyone is enjoying their time chillin' and... well, chillin' some more! Apart from the odd monster, everything is at peace. Man, this is the life. Percy has some BIG plans for Annabeth, and they cannot be thrown away! Taking advantage of this peace, Percy is gonna put those plans in ACTION! Nothing can stop him! Not even wizards! Pffft. Wizards. Hilarious. Whoops. Spoke too soon. Apparently, there WERE wizards who are ruining his fun. Great. __________________________________________ Harry has just defeated that party pooper baldy, and DAM does he feel great about his achievement. However, Dumbledore just HAD to find out that Voldy has a grandson, a powerful one indeed. Unable to put away his past, Harry just cannot forgive this 'grandson', not after what that monster Voldemort did... TWO favourite worlds crash together, and man the outcome will not be pretty. Uhhhh... am I suppose to say, uh, more? Um... this is my first story, and I hope you enjoy it. Peace out people, and try not to kill yourself!

Hey guys, this is a Harry Potter/PercyJackson crossover! Here's the prologue( this won't be in the book): Sally Jackson, a young orphaned girl, was took in to the home of two magical beings, where she found out she was a witch. She was adopted by a witch named Laura Jackson and a wizard named Jim Jackson. They took care of her until figuring out her real father Voldemort. Sally went to Hogwarts and was placed in Gryffindor. She quickly befriended Lily, and they became best friends. Sally joined the order, and one evening told everyone about her father. No one believed that such a nice and brave witch could have such a horrible father. Lily and James never took that in consideration and when she was away to an order meeting, Harry was orphaned. No one trusted her, so she ran away to America. This is the story of her son, Perseus Jackson A/N: This is after Order of the Phoenix and Heroes of Olympus Sirius didn't die, instead Peter Pettigrew did! A/N: This used to be called 'Perseus Jackson, Voldemort's Grandson'
