Set After heroes of Olympus, during half blood prince, Percy Jackson and some of his friends must go to Hogwarts to help Harry Potter against Voldemort in the war. Through their many hardships the two completely different groups have to work together despite their differences to win this war. Will they fight, or unite? Disclaimer; I do own characters they are the work of JK Rowling and Rick Riordan There will be spelling and grammer mistakes but I can't be bothered to fix it.

This story is about how the seven plus Nico and Thalia learn they are more than the average demigods. They go to a new school for wizards and witches and befriend the golden trio, Harry Potter, Ronald Weasley, and Hermione Granger. Everyone gets settled down to a peaceful life just to be disrupted by a rising new threat. Will they beat this unknown threat or will they die trying? Who will be the side that claims victory? Good or Evil? DISCLAIMER!!!******* I don't own the PJO or HP characters They belong to Rick Riordan and J.K Rowling!!!!!*********

Percy Black lost his mother, Sally Black, at a young age, and never knew his father, he is raised by his Aunt Narcissa and uncle Malfoy to be a proper pure-blood but hes not sure he wants to be one. Hes faced with a choice (Crappy summary I know but I was never able to explain my work) Under editing

I have read so many Percy Jackson and Harry Potter crossovers that I can't even begin to count the number. My problem is that they are most of the time the same story. Authors tend to use the same plots over and over. This fanfic is written to try to shake things up. The major difference, Harry and Hermione are going to Camp Half Blood. (I am hoping this is a semi-original idea) It's just a twist on the typical crossover and I hope you enjoy!

This is a Percy Jackson/Harry potter crossover. I have only made up a few characters but they will not be a main character or anything their just there to make the story work. The war with Gaea is over, Percy and Annabeth finally think the fates ( and Aphrodite ) will leave them alone to continue their lives in peace, obviously they were wrong. Now the seven, Will, Nico, Thalia and calypso have to go on a quest to the wizarding world. ( hey this isn't the best summary but read the book it will be much better )

Percy gets a letter from Hogwarts asking him to attend the school for sixth year after his holidays.What happens when the two worlds crash? Takes place after the Giant War and Wizard war.

What will happen when our favourite demigods go undercover and meet our favourite wizards? Can they stay hidden? Are any wizards actually demigods. This is a PJo/HP crossover. Advice is wanted so comment and stuff.

The seven plus Nico, Thalia and Calypso are going Hogwarts to protect the golden trio from the war that is coming. The combined forces from Gaea, Kronos and Voldemort are planning to attack Hogwarts and Camp Half-blood by the end of the year at Hogwarts. Read to find out what happens. A/N: I am horrible at descriptions I promise the story will be better and also I do not own PJO, HoO and HP the two amazing authors JK Rowling and Rick Riordan do. I only own the plot and any characters I make up *This takes place after the Deathly Hallows and BoO and Dumbledore, Fred, Tonks, Snape and Remus and anyone else that died in deathly hallows is gonna be alive ok*

"He saw a almost identical boy a few feet away from him. The only difference was that he had a small scar shaped like a lightning bolt on his forehead a glasses. Percy walked closer to him, realizing that he noticed him too" If you're a Potterhead AND a PJO/HOO fangirl/boy then this book is for you! Read to find out what happens next.... The character Percy Jackson and the other demigods are owned by Rick Riordan and The character Harry Potter and the other wizards are owned by J.K Rowling, thus other characters belong to the author of this book/me! The dragon belongs to the amazing artist viria and I only did a little change to Percy's mouth to make him smile.

'Seven come forth again To make peace with another Against the dark wizard And the earth mother Son of Poseidon And the chosen one Shall fight side my side Till the battle is won' Percy Jackson and the seven have to become allies with the wizards of Hogwarts to defeat two enemies who have risen again. With war upon them, they have to make peace before it is too late.
