One way...or Another

Percy Jackson: Camp Halfblood's best demigod, boyfriend of the smartest girl in the world, been successful in all his quests.

Harry Potter: The most powerful wizard ever since he survived the killing curse, killed Voldemort the most horrible guy in the world and is repeating his seventh year at Hogwarts.

Little did these two boys know that these two worlds have been secretly at war since Camp Halfblood apparently stole Pandora's Box which is needed to keep the wizarding world away from war. Disputes are rising. Families are fighting against eachother, taking sides. The Ministry of Magic is going to put a stop to this. They contact the Camp at Long Island and begin to find the perfect selection of demigods and wizards to defeat the power hungry goddess who has stolen the box.....NEMESIS.
